How to identify garage door opener problems
Is your opener giving you trouble? Does the door not open all the way, or not respond to the remote? Usually the problem is easy to identify and the solution is not complicated.
Some issues you can fix on your own; for others you need a professional. Please don't experiment too much with the opener: a small mistake can cost you a lot. Try a repair only if you are confident about what you are doing.
The most common garage door opener problems
1. The opener doesn't respond to the remote or the wall switch
If the door doesn't move at all when you press the remote or the wall switch, the electrical supply may be interrupted. First check that the opener is plugged in. Then make sure the fuse, the GFCI outlet or the circuit breaker hasn't tripped. It is also possible that the opener's motor has burned out.
Our technicians handle all of these: wiring, short circuits, and replacement of a dead motor.
2. The door doesn't open with the wireless keypad or the remote
There are many reasons a door won't respond to the remote or keypad. The first is range: a few feet of distance can hamper the signal, so try moving closer. If the door works from the hardwired wall switch, the problem is the remote itself, usually the batteries in the keypad or remote.
If none of that helps, a professional will reprogram the remote and check for other issues.
3. The door reverses as soon as it touches the floor
If the door leaps back up right after hitting the floor, the close-limit switch is off. A misadjusted limit screw can make the door reverse before it reaches the floor, or not close all the way.
Our technician adjusts the close-limit screw on the opener motor and checks the safety sensors so the door closes properly. We check this carefully on every opener installation so the issue doesn't come back.
Questions we get about this job
Why doesn't my garage door opener respond to the remote or the wall switch?
Usually power: an unplugged unit, a tripped GFCI outlet or breaker. If power is fine, the motor or logic board may have failed.
Why does my garage door reverse when it touches the floor?
The close-limit adjustment is off or the safety sensors are misaligned. Both are quick adjustments on a service visit.
