How to Tell that Your Garage Door Opener is Broken

How to Tell that Your Garage Door Opener is Broken

Steps to Help Assess if Your Malfunctioning Garage Door Opener Needs Repair

To the casual observer, it may at first be testing to find any similarity between automatic garage door opener and major household utilities like hydro, water, and gas.  Let’s face it; the former is a mechanical device while the latter are fundamental services that help make a home inhabitable.

Upon closer inspection though, there are some similarities when comparing garage door openers with public utility services, principally with respect to convenience and reliability.  At basically the flip of a switch or the push of a button, one can open/close their garage door just as easily as they can turn on a television or pour a glass of water – that is the convenience factor.  From a dependability perspective, the garage door opener responds each time and every time, in the same way, that the lights always come on and the bath always has hot water.

This is why it is bewildering when any of the above comforts fails to respond; a failure is so unforeseen, it leaves a homeowner and their family members essentially in disbelief, not to mention that it is often highly disruptive to their daily routines.  And in the case of a garage door opener, Murphy’s Law dictates that it will stop functioning at the absolute worst possible time to have a car trapped in the garage.

It is important to note that, when a garage door will not open, it should not be assumed that it is the automatic opener that needs repair – the issue could lie with the device or with the door itself.  To determine the source of the problem, homeowners may actually want to begin by examining the door for one or more of the following indicators:

  • Broken spring
  • Damaged rollers
  • Loose/broken cable
  • Bent/blocked tracking
  • The door is out of alignment
  • The door is frozen shut (winter)
  • The door cannot be opened manually

If in fact the garage door can be opened manually, and rather easily, then the problem most likely resides with the door opener.  In this instance, homeowners can test various aspects of the opener to assess whether its functionality can be re-established or if there is a need for repair or replacement services.  These do-it-yourself measures can include:

  • Checking for a tripped circuit breaker
  • Confirming the connection to the power supply
  • Resetting the unit – unplug it, wait, re-connect it, try again
  • Changing/testing remote batteries to see if there is a response

If the above actions are unsuccessful in isolating the issue and/or restoring the operation of the garage door opener, it would be prudent for homeowners to call the garage door service professionals at Markham Garage Doors to determine the best course of action.

Consider the LiftMaster Series for Your New Garage Door Opener Installation

In some instances, depending on the type/extent of the repair work needed, it could be more cost-effective for homeowners to move forward with the installation of a new and upgraded garage door opener; when a full replacement is a better/preferred option, it is advisable to consider the LiftMaster line of garage door openers.

When Your Garage Door Opener is Getting Power But the Door Will Not Move

Trained Garage Door Installers Can Help Identify Issues with the Door Opener

When asked, any homeowner with a garage door opener will quite likely certify that such a device offers several benefits to their family.  It would not take long, perhaps within a day after the installation, for that homeowner to wonder aloud about why they waited so long to take advantage of the conveniences that they now enjoy with respect to entering and exiting their garage.

Additionally, the garage door opener can provide a number of security measures for both the family and their personal possessions, and although there are high hopes that there will never be any type of unwanted intrusion through the garage, the peace of mind from such protection can be quite tangible.  When the convenience and security of a garage door opener are added to its durability/reliability, there are valid reasons to believe that the homeowner has made a wise investment for the next 10 to 15 years; this lifespan is based on an average of 1,000 to 1,500 opening-and-closing cycles per year.

Despite this dependability, however, there can be times when the convenience and the security of a garage door opener can be at odds; one such case occurs when the garage door opener is getting power (its light comes on) but the door itself does not open when commanded.  While this may be great for security, it can be particularly inconvenient for the person who wants/needs to enter or exit the garage.

When a garage door opener appears to be working/active but the door does not move, it likely means that the issue lies somewhere other than the power source. Subsequently, it would be advisable to investigate the following to try and pinpoint the root cause:

  • Disconnect switch – has the rope or knob been unhooked accidentally?
  • Garage door lock – (common with older doors) has it been engaged?
  • Tracking – is any door movement being hindered an object/obstacle?
  • Opener – is there an issue with the capacitor, motor, or drive system?
  • Garage door spring – it is broken, or has it lost some/all of its tension?

Some of the above assessments can certainly be completed in do-it-yourself fashion, and if they identify the cause of the problem, the respective remedies can also be done by the homeowner.  However, in the event that an issue is unidentifiable, more complex, or directly related to the garage door spring, it would be prudent to turn to the expertise of a professional garage door services provider such as Markham Garage Doors.

The technicians from Markham Garage Doors have considerable experience with both the installation and repair of garage door openers and can apply that familiarity to determine the source of the problem and perform the necessary repairs or perhaps recommend the installation of a replacement opener.

Consider These Handy Accessories for Your Garage Door Opener

Garage Door Opener Accessories Provide Added Safety, Security, Convenience

The introduction of the automatic garage door opener was indeed ground-breaking in its own right; it permitted drivers and family members to open and close their garage door without actually touching the door.  This was, and still remains, a convenience for many people, especially when they arrive home in wet, cold, and/or windy weather conditions.

Garage door openers have certainly come a long way since their rudimentary beginnings.  While their principal function of a garage door opener remains the same – to open and close a garage door – their level of sophistication has grown exponentially, thanks in large part to advancements in technology, but also due to an inherent need/desire to extract wider/added functionality from a single device.

Here are some handy garage door opener accessories that may appeal to current owners of these devices, or perhaps offer enough appeal for a homeowner to have one installed:

  • Wireless exterior keypad – operates the door from the outside, based on a four-digit code; convenient access without a remote or a key e.g.: children arriving from school
  • Wireless monitoring system – allows homeowners to control and operate their garage door opener anytime, and from anywhere in the world, using a smartphone or tablet
  • Garage door monitor – check the status of a garage door before retiring for the night
  • Mini-remote – fits on a key ring/in a purse; improves security – no remotes left in the car
  • Laser parking system – helps establish where to stop/park vehicles upon entering the garage; also indirectly delineates/maximizes storage space along the back wall of a garage
  • Battery backup system – allows access to/exit from the garage during any power outage

By integrating such types of accessories with their garage door opener unit, homeowners can benefit in a number of ways, including:

  • Improvements in home security
  • Enhancements in personal safety
  • Added convenience in daily routines

Differentiating the Chamberlain and Craftsman Brands of Garage Door Openers

Chamberlain and Sears Craftsman Garage Door Openers Have a Lot in Common

Once considered to be more of a novelty item, or perhaps even a luxury in some circles, garage door openers have become a common amenity for many homeowners. Whereas people at one time might have marveled about the one mechanically-operated garage door on their block, they seldom give it any thought should they happen to see someone driving in or out of a garage without exiting the vehicle to open/close the overhead door.

Garage door openers have indeed become a modern convenience for many homeowners and their families. And, as with many other mechanical devices, advances in technology have taken garage door openers, metaphorically speaking, to greater heights. Today’s automatic openers offer much more than just convenient access to/egress from a home or garage, as manufacturers are integrating technology that provides such features as:

  • Low-noise operation
  • Smartphone activation
  • Advanced security options
  • Battery back-up functionality
  • Operation via fingerprint recognition

There are in fact several makes and models of garage door openers on the market and choosing one over all others may at first seem to be a somewhat overwhelming/daunting task. However, upon closer inspection, an immediate delineation can be made between brands like LiftMaster, available only from licensed distributors such as Markham Garage Doors, and those that can be acquired commercially, most notably the Chamberlain and Craftsman product lines. For the purposes of this discussion, comparisons will be limited to these latter two brands only.

Perhaps the most distinguishing characteristic between these two brands is the means in which they are made available to consumers. Craftsman garage door openers have been associated with and sold exclusively through Sears outlets whereas Chamberlain models can be bought from many different home improvement, hardware, and wholesale stores. Another differentiating aspect is seen in product types: both brands include screw-drive, belt-drive, and chain-drive formats, although only Chamberlain offers a jackshaft or wall-mounted option.

On the other hand, perhaps the least known characteristic about these brands is the fact they are actually manufactured by the same company – Chamberlain. That’s right, the Craftsman garage door openers are private-label devices made by Chamberlain and sold by Sears under its own Craftsman brand name.

Since Chamberlain and Sears Craftsman garage door openers are produced by the same company, it stands to reason that these product lines would have numerous similarities. As a result, their most popular features in common include the following:

  • A variety of models and prices to accommodate all needs
  • Do-it-yourself installation for homeowners who are so inclined
  • Ease of operation, with smooth and essentially silent drive systems
  • Powerful motors – up to ¾ horsepower to left the heaviest of doors
  • Standby power systems – to continue operating during hydro outages
  • Extension kits to fit non-traditional garage door heights (over seven feet)
  • Compatible with MyQ smartphone technology (worldwide connection/control)
  • Rolling code technology for enhanced home security and burglary protection

Despite their many similarities, it appears that the Chamberlain product line may have a slight advantage based on consumer preference. This includes assessments across such comparators as:

  • Basic affordability – Chamberlain PD210D
  • Power and strength – Chamberlain PD752D
  • Ultra-quiet operation – Chamberlain WD822KD

And just a last word overall – although Chamberlain and Craftsman garage door openers offer the option/flexibility of do-it-yourself installation, this route may entail a degree of complexity, especially in relation to setting up any wireless technologies and/or adjusting high-tension springs and cables. As a result, homeowners may instead choose to call on the expertise of an installation specialist from a reputable service provider like Markham Garage Doors.

Get Professional Advice from the Experts in Garage Door Opener Installation

When choosing a garage door opener, homeowners will need to take several factors into consideration. In addition to baseline aspects such as cost, noise reduction properties, overhead clearance space, and the anticipated frequency of use, assessing the following can and often will influence an ultimate decision:

  • Design – overall horsepower, dependable operation, compatibility to technology
  • Hardware – accessories such as keypad entry, keychain remotes, track strength
  • Warranties – what is covered by the manufacturers and for what length of time?
  • Safety and Security Features – auto-reverse mechanism, anti-access capabilities
  • Customer Service/Support – owner’s manual, a service department, onsite repairs

Whether the intent is to purchase a Craftsman or Chamberlain garage door opener from a retail outlet or a LiftMaster model for professional installation, homeowners must make an informed decision to ensure the best possible return, and performance, from such an investment. The Markham Garage Doors team can be a valuable asset to homeowners with respect to making the right choice of garage door opener for their personal needs and type of door, as well as its installation and any subsequent service or maintenance.

How a Garage Door Opener Works

The Role of a Garage Door Opener in Raising and Lowering the Door

There is little doubt that a garage door opener has become a modern convenience for many homeowners, allowing them to drive into and out of their garage without the need to exit the vehicle to lift or lower the door.  This is certainly a handy amenity in times of inclement weather as well as a safety feature when arriving home after dark.

In most cases, these homeowners simply push a button on a remote control device then wait for the door to open or close without giving this action a second thought.  So it may be surprising to many people when they learn that a garage door opener actually does very little in terms of moving the door up and down.  Yes, the door opener does provide a small amount of force to control how far the door travels when activated automatically, but it is the tension stored in the garage door springs that really does most of the heavy lifting and lowering.  In addition to its ‘prompting’ of the springs, a garage door opener can act as a lock when a door is in the closed position.

With respect to its basic operation, a garage door opener consists of the following major components:

  • An electric motor housed within a power unit attached to the garage ceiling
    • Wall-mounting the unit to the side of the garage door is also an option
  • Tracking extending from the power unit and secured above the garage door
  • A trolley connected to an arm which is in turn attached to the top of the door
  • A drive system to move the pulley along the track when the motor is in operation
    • A system is usually belt-driven, chain-driven, or screw-driven

Improvements in Remote Access Security

When garage doors openers were first introduced and began growing in popularity, users encountered issues in terms of security or, more accurately, a lack of security with their remote controls.  Initially, this resulted from the limited number of frequencies that were being shared between transmitters (remotes) and receivers (door openers); when this situation was rectified through the introduction of multi-code systems, security was quite basic and thieves were able to ‘crack’ these codes rather easily.

Today, the security features of a garage door opener are truly state-of-the-art, as the major manufacturers strive to deliver the highest quality performance combined with the greatest degree of home impenetrability.  Some of these high-tech components include:

  • Wireless keypads
  • Keychain remotes
  • Rolling code technology
  • Solenoid-operated deadbolts
  • Smartphone-controlled activation
  • Fingerprint-based wireless keypads
  • Remote lockout (receiver turned off during absences)

A garage door is frequently and repetitively in motion, usually performing two or more open-and-close cycles each and every day.  Therefore, a properly installed garage door opener can indeed be a valuable asset to any homeowner, from the standpoints of both personal convenience and improved home security.

Garage Door Opener Installation by Certified Experts at Markham Garage Doors

Based on the number of times that an automatic opener will be commanded to open and close a garage door, the device and its accessories will need to be reliable and durable.  In addition to the quality of the actual unit/motor, a critical factor in ensuring consistent and long-term performance will be the standard of garage door opener installation.

The trained technicians at Markham Garage Doors are manufacturer certified to install LiftMaster, one of the leading brands worldwide for over 45 years.  The LiftMaster product line is well recognized for its combination of performance with the ultimate in safety and security features.  This series is not available through commercial means but rather is distributed via licensed dealers such as Markham Garage Doors.

When to Consider a Wall Mount Garage Door Opener

A Wall Mount Garage Door Opener Offers Unique Flexibility and Benefits

Many homeowners with a single car garage may often be heard bemoaning the fact that they should have purchased a home with a double car garage in order to give them more storage space.  This restricted space can become particularly frustrating if they choose to park a vehicle in the garage, as they may have to move it out to the driveway every time they want to access the lawnmower, snowblower, gardening equipment, or their children’s bicycles.

What is interesting in such a scenario is that homeowners with double car garages have the same lament.  They still do not seem to have enough space for everything that they want to store in their garage regardless of where they park their vehicles.  And to further complicate matters, for either a single car or double car garages, installing a garage door opener can restrict the clearance space/storage space near the ceiling as well.

In the types of circumstances where homeowners may want to have a little more storage space in their garage yet still enjoy the conveniences of an automatic opener device, the ideal solution may be the installation of a wall mount garage door opener.

There are several reasons why a wall mount garage door opener may be preferred versus the more traditional/more common ceiling mounted model.  These might include:

  • To maximize the use of available off-the-floor storage space/room
  • To allow added height for a lifting device (do-it-yourself auto care)
  • To clear ceiling space for another device (a hoist or pulley system)
  • To accommodate garages with low ceilings or irregular dimensions
  • To compensate for garages that cannot support overhead tracking

A wall mounted model may also be called a jack shaft garage door opener.  It is primarily installed on the wall immediately to the left or right of the garage door, provided there is a nearby power/electrical outlet inside the garage.  This wall unit is merely attached to the garage door’s torsion bar, eliminating the rails that are customarily used to connect ceiling mounted openers to garage doors and thereby creating more overhead clearance.

Due to its uniquely different installation and operation from a conventional chain, belt, or screw driven garage door openers, it is highly recommended that homeowners utilize the installation services of a professional supplier and installer like Markham Garage Doors to correctly mount their jackshaft garage door opener.

LiftMaster Elite Series 8500 Wall Mount Garage Door Opener is an Ideal Option

The most common and reliable jackshaft style device is the LiftMaster Elite Series 8500 wall mount garage door opener.  The sleek design of this unit takes minimal space itself upon installation while offering all of the space-saving flexibility and benefits noted above – along with reliable performance and ultra-quiet operation as well.

The LiftMaster Elite Series 8500 wall mount garage door opener also has additional features which may/will appeal to homeowners based on need and personal preferences.  A small sampling of these features/options would consist of:

  • Connectivity – technology to control the door opener through a smartphone
  • Performance – lifetime warranty on the motor; five-year warranty on parts
  • Safety/Security – audio and visual alerts when the garage door is about to close
  • Accessories – three-button LED remote control; remote wireless ceiling light

To ensure proper functionality and adherence to warranty applications, the LiftMaster Elite Series 8500 wall mount garage door opener should be installed by a trained garage door service technician.  Markham Garage Doors is a licensed dealer for the LiftMaster brand of garage door openers, and their technicians can, therefore, be trusted to install any and all LiftMaster models efficiently and reliably.

A wall mount garage door opener may be the ideal solution to maximizing the available space in your garage.  Call Markham Garage Doors today at (905) 472-9178 or (416) 570-3667 to arrange a no-obligation consultation to discuss the suitability of the LiftMaster 8500 to your specific needs.

Fixing a Broken Garage Door Opener

Consider These Do-It-Yourself Repairs for a Broken Garage Door Opener

Garage door openers are generally quite dependable and, under normal usage patterns and with regular maintenance, homeowners might expect the lifecycle of their opener to span roughly 10 to 15 years.  For the record, average usage rates are usually considered to range between 1,000 to 1,500 opening-and-closing cycles per year.

In fact, the dependability of a garage door opener can lead to homeowner complacency.  Push the button on the remote, the door goes up/down, and their daily routine carries on without a second thought about the operation of the door opener – what could be easier?

Then one day, totally unexpected, there is no response when someone tries to activate the door opener.  The door does not move and, despite repeated attempts and maybe a change of batteries, a grim realization sets in – the issue at hand might be a broken garage door opener.

To be certain, however, homeowners should confirm rather than assume that they have a broken garage door opener.  This can be done as follows:

  • Checking the power supply – is everything actually on?
  • Testing all remotes to see if there is any response at all
  • Changing batteries in all remotes and trying them again
  • Determining if the opener will respond to the wall switch
  • Re-programming (unplugging then re-connecting opener)

If in fact the issue can be linked or traced back to the automatic door opener itself, there are certain basic repairs that homeowners may wish to considerwhich can include a garage door cable change, and/or perform on their own, depending of course on the identified problem.  Such actions might include:

  • Cleaning or replacing the safety sensors at the base of the rails
  • Replacing the circuit board (motherboard) for their specific unit
  • Exchanging the gear shaft-sprocket assembly on the drive shaft
  • Checking and re-securing or replacing loose or damaged wiring
  • Swapping the existing screw drive coupler for a new component

On the other hand, if homeowners suspect that they have a broken garage door opener but cannot pinpoint the source of the problem, they may wish to call upon the expertise of a professional garage door repair provider, such as Markham Garage Doors, to help diagnose and rectify the situation.  This would also apply to circumstances where there is some hesitation on the part of the homeowner to address any garage door opener issues on a do-it-yourself basis.

Some Garage Door Repairs Should Be Entrusted to Trained Professionals Only

When a garage door opener is not working properly, it may be the result of an issue with the door or its parts rather than the device itself.  In these cases, attempting to operate the opener may lead to more extensive damage and expensive repair/replacement costs.

There are several factors that may directly or indirectly contribute to the malfunctioning of an automatic garage door opener.  Such causes may consist of:

When the above types of situations are encountered, it is advisable that homeowners forego any do-it-yourself measures and contact an expert in garage door repairs, like a trained service technician from Markham Garage Doors.  This is especially true when dealing with high-tension springs/cables or out-of-balance door weights, to eliminate any risks of personal injury.

How to Adjust Chamberlain Garage Door Openers

Ways to Keep Chamberlain Garage Door Openers Working at Optimum Levels

In the vast majority of cases, Chamberlain garage door openers will open and close smoothly and efficiently each and every time they are so required. It is also generally accepted that the lifecycle for these garage door openers should be roughly 10 to 15 years, assuming a performance rate ranging from 1,000 to 1,500 open-and-close cycles annually.

When the aggregate number of multiple-year cycles is taken into consideration, it can certainly have a toll on garage door openers, simply due to the vibrations of normal operation as well as the repeated effects of starting and stopping basically on demand. Therefore, notwithstanding their seemingly routine operation, Chamberlain garage door openers might need some periodic adjustments to ensure that they continue to work at optimum levels as long as possible. Specifically, this means paying attention to:

  • The travel limits of the door upon opening and closing
  • The force required to activate the safety mechanisms

Any and all tests and adjustments can be performed in do-it-yourself fashion and should be completed on at least an annual basis. The process also applies to all Chamberlain garage door openers regardless of the drive system or horsepower.

In terms of actual tools, very little is required:

  • A step ladder
  • A slotted screwdriver (often called a flathead)
  • A properly functioning garage door remote control

Perhaps the most important element to performing any tests or adjustments will be the presence of a partner. Equipped with the above items, the team can proceed as follows:

  • Establishing the travel limits of Chamberlain garage door openers
    • Note – adjustment screws are on the left side of garage door opener motorheads
    • Note – one full turn of these screws equates to a door travel distance of two inches
      • Setting the up-limit
        • Position ladder below the back or rear portion of the opener to access the screws
        • Open door using remote – bottom of door should come to rest just below header
        • If door does not stop in this position, an up-or-down adjustment is likely required
        • Turn the up-limit screw clockwise to raise door or counter-clockwise to lower door
        • Using remote, close door then re-open to check travel – repeat process if needed
      • Setting the down-limit
        • Once travel limit has been adjusted for the open position, close door using remote
        • Door should close tightly to the garage floor without gaps (no penetration of light)
        • If there is a gap, adjust down-limit screw accordingly (counter-clockwise) to lower
        • Using remote, open door then re-close to check travel – repeat process if needed
        • Door will automatically re-open if adjusted too far (safety mechanism is engaged)
        • Readjust down-screw – turn clockwise to change travel limit for the down position
  • Testing the activation of safety mechanisms with garage door openers
    • Note – these adjustment screws are on the upper right side of garage door openers
      • Setting the up-force
        • Place ladder below lens side of opener to access these screws (under lens cover)
        • Ask partner to stand outside the door – this test should begin with door closed
        • Open door using remote – at approximately the half-way point, and with the door in motion, partner should gently clutch bottom of door and apply some downforce
        • Door should basically stop moving immediately when encountering the obstruction
        • If undue force must be applied before door stops, up-force adjustment is needed
        • Turn up-force screw slightly counter-clockwise – return door to the closed position using the remote and repeat test as needed until desired safety result is achieved
      • Setting the down-force
        • Once up-force has been correctly adjusted, use remote to open door completely
        • Once again, ask partner to stand in position just outside the garage door opening
        • Lower door using remote – at approximately the half-way point, and with the door in motion, partner should grasp bottom of door and pull upward slightly
        • Door should stop moving immediately and then automatically reverse
        • If door does not immediately stop and reverse, down-force adjustment is needed
        • Turn down-force screw marginally counter-clockwise – return the door to its open position using the remote and repeat test as necessary to achieved desired result

If any of the above adjustments are proving to be a challenge and/or sensitive in nature, homeowners have the option of contacting an expert in the installation of Chamberlain garage door openers, such as a trained technician from Markham Garage Doors.

What To Do When Your Garage Door Opener Stops Working

Troubleshooting Garage Door Opener Issues Can Help Avoid Service Call Costs

When a new garage door opener is first installed, homeowners might have the realistic expectation that the device will operate flawlessly, day after day, for many years. And in all probability, a garage door opener should perform for approximately 10 to 15 years, based on an average of 1,000 to 1,500 open-and-close cycles per year.

But how many people actually keep track of the number of times that their garage door is opened and closed in a day, let alone over 10 to 15 years? Furthermore, what is the percentage of homeowners who can easily recall the year that the opener was installed?

In the majority of cases, it is likely that homeowners simply expect their garage door to open or close every time they pull into the driveway and use the remote. So, when the day arrives that the garage door opener does not respond, they often stare at the remote in a state of disbelief.

However, all problems encountered with a garage door opener cannot be attributed to one source only. The cause of the problem may actually lie with any of the following:

  • The garage door opener unit
  • The remote control device(s)
  • An electrical or wiring issue

When the garage door opener does not respond as expected, there are several ways to troubleshoot the situation prior to accepting or conceding that the unit either needs to be repaired or replaced. In many instances, a little time, patience, and investigation, as outlined below, can save a large amount of money:

  • Garage door opener does not respond to the remote – check:
    • Batteries in the remote – weak or fully spent?
    • Battery voltage – sufficient to power the opener?
    • Battery contacts – corroded, discolored, wet/damp?
    • Infrared eyes on remote and opener – scratched, broken, dirty?
    • Frequency setting for the remote – aligned with the unit’s receiver?
  • Garage door opener does not respond to remote or wall-button – check:
    • The power source to determine if it is properly plugged in
    • For a blown fuse or tripped breaker in the electrical box
    • That the infrared safety sensors are in the proper alignment
    • For signs of a recent power interruption – may need a simple reset

As noted previously, a garage door opener can have a life expectancy in the range of 10 to 15 years depending on the quality of the unit and its frequency of use. However, this does not mean that hiccups, like the situations described above, will not occur over that time period. If such issues cannot be found and resolved as a result of homeowner troubleshooting, a trained technician from Markham Garage Doors may be required to provide professional diagnostic and repair/replacement services.

Garage Door Opener Issues May Extend Beyond Dead Batteries In The Remote

When a garage door opener stops working, it may seem too simplistic to suggest that the cause may be due to batteries in the remote or a blown fuse – but the solution is often something just that basic.

Unfortunately, this is not always the case, as a non-working garage door opener might be due to any number of reasons not immediately identifiable by the homeowner. These causes may be related to:

      • The drive system
      • Horsepower issues
      • A power surge or failure
      • Overall garage door weight
      • An out-of-balance garage door
      • Attempts to open a frozen door
      • Accidental damage to the door
      • Weather extremes

A Garage Door Opener Provides Convenience Plus Durability And Safety Options


In some ways, an automatic garage door opener can be likened to a cellphone, central air conditioning, or a television remote control. People may not appreciate the levels of comfort and convenience offered by such amenities until the day comes when they push the appropriate button and, lo and behold, nothing happens. It would almost seem like the device arbitrarily, and without warning, can just decide when it shall work no longer.

However, when a garage door opener is working properly, it may come as a surprise to learn that the device itself does not actually lift or open the door. The lifting force is provided by the spring that is attached to the door, most often a torsion spring, which is designed and used to counterbalance the weight of the door via a significant amount of tension. When the garage door opener is activated, either through a wall switch or by remote control, its primary role is for regulating the speed and distance that the door travels/moves to fully open or close. Furthermore, a garage door opener can keep a door securely closed in lieu of a lock-and-key method.

Garage door openers operate using one of three basic types of mechanisms or drives:


  • Perhaps the most common as it is the least expensive mechanism
  • It is also the loudest of the three options (rattling noise of the chain)


  • The quietest option (fewer moving parts) but also the most expensive
  • A good choice when the garage is either below or next to living space


  • Comparatively quiet – a good choice for heavy, double-width doors
  • Also requires the least maintenance (has the fewest moving parts)

Another aspect of automatic garage door openers that is often misunderstood pertains to their safety, or more specifically, to the safety of the occupants of the home and their personal property. Through significant advancements in technology, since they were first introduced, security features have improved in the following ways:

Rolling codes for remote control devices

  • A new code is generated each time the remote sends a signal to the receiver
  • There are literally millions of possible combination per garage door opener
  • Code hackers/thieves are therefore unlikely to access the home in this way

Electronic eyes (or photodetectors)

  • System employs a light beam transmitter plus a receiver at the base of the door
  • Obstruction of the light beam by a person or object prevents door from closing
  • This system should also trigger an auto-reverse mechanism for such instances

Wireless keypads

  • They can be activated using a personal identification number
  • Family members can open and close the door without a key or a remote

Like most other devices that have moving parts and/or electronic components, a garage door opener has a finite life expectancy. Factors that can/will influence the operating life of an automatic opener include:

  • Amount of daily use
  • Quality of the device
  • Regular device maintenance
  • Regular door maintenance
  • Proper door balance

In all likelihood, and with proper care and maintenance, a garage door opener should perform for roughly 10 to 15 years, based on an estimated 1,000 to 1,500 opening-and-closing cycles annually. Eventually, fundamental wear-and-tear can cause the device to break down and cease to function in a proper and expected manner.
