It’s not too hard to pinpoint why your garage door opener is malfunctioning, nor is it too much effort to troubleshoot.
Below are a few of the most common garage door opener problems, as well as respective repair methods.
Keep reading if you’ve been wondering how to adjust garage door opener!
Note that should your overhead door opener issues fall into none of the following categories, don’t hesitate to get in contact with a licensed company for your needs!
Wall switch and remote control “stop working”.
Check if your motor unit is plugged in properly before searching for other causes.
If plugging isn’t the issue, take a look at the fuse, circuit breaker, or GFCI outlet to see if it’s burned out or has a faulty door opener circuit.
This is the likeliest cause should your other electrical circuits or lights appear problematic too.
Your GFCI or breaker will then need resetting.
Should repeated tripping continue afterwards, your system could have short-circuited.
In the case that the motor to your garage door opener/your fuse itself is entirely burned out, you won’t have to learn how to adjust garage door opener, as you will simply need it replaced.
Unresponsive to keypad and remote control.
First check if you’re simply beyond antenna-range; some garage doors perform at around 315mH, making them easily affected by even a little extra distance.
Your keypad/remote control batteries probably need replacement if your overhead door responds just fine to the wall switch but not to them.
Regardless, ensure that the motor unit’s antenna isn’t broken or hanging down.
You could also reprogram your keypad or remote control as these devices are prone to losing programming now and then.
This can be done quickly if you follow their specific instructions.
Incomplete opening of garage door.
Investigate if your rollers are uncooperative, then lubricate or replace them as needed.
You may have to move your up-limit switch (a touch-lever secured to the end of the track) towards the motor unit.
If this is too far off, the motor stops your garage door before it opens entirely.
Motor continues running even after overhead door opens.
This issue is less common, but usually indicates that your up-limit switch has to be moved further off from the motor unit.
Incomplete closing of garage door.
Adjust limit switches.
A close-limit switch protects people from getting into garage door-related accidents.
A simple adjustment can keep this vital component from malfunctioning.
Set-limit switches are responsible for letting the garage door motor know when it’s time to stop running.
To adjust your set limit switch, simply turn the motor unit’s screw feature to set how far down you need your door to close.
Realign/readjust safety sensors.
Check that the sightline between the electronic eyes found on the bottom of your door track is clear of blockages.
A garage door may refuse to close correctly if electronic eye brackets are misaligned, or if there are disturbances in their sightline.
If this is a consistent problem, it could be that the door’s vibrating movement in the tracks loosens the sensor brackets, meaning you’ll have to align them accordingly.
Additionally, you may find that your tracks are bent/shifted, or that your rollers are rusty.
Rusted rollers often get doors to bind in their tracks.
If the problem can’t be solved with silicone lubricant, simply switch yours out.
Reversing overhead door.
If, before hitting the floor, your garage door reverses, it could be due to one of the following problems.
The adjustment screw on garage door openers control closing forces.
Your close-force setting might need lowered sensitivity, as door roller friction in the tracks can trick the door opener into thinking contact has already been made with the floor.
Furthermore, excess friction can be caused by rusty rollers, once more prompting your door opener to stop early.
Lubricate your rollers and keep them in good condition to avoid this.
On the other hand, if your overhead door immediately reverses upon floor contact, this could be a close-limit switch problem as well.
Carefully adjust its screw until the door finally comes to a stop once it touches the floor.
