Broken garage door? Sometimes it can be difficult to pinpoint the problem—and know whether or not the repair is something that you can do yourself. Here is a guide to troubleshooting your garage door so that you can know what exactly is causing the problem.

Is the torsion spring intact?

The long torsion spring located above your garage door is central to your garage door system. Is it intact? If it is broken in the middle, then you know it has worn out and needs to be replaced. (Working with torsion springs is very dangerous, so be sure to talk to a specialist here.)

Does it open and close manually?

Pull the release cord on your garage door and manually lift the door to see if it opens and closes smoothly. It it doesn’t, then you know there is a problem with the tracks, rollers, or springs—and not with the opener.

If the door does open and close smoothly, then the problem is something else. Leave the door down and re-engage the emergency release for further troubleshooting.

Does the remote work?

If your garage door doesn’t respond to your remote, try opening and closing your garage door using the wall switch. If your garage door opens and closes, then you know it is a problem with your remote. That could be as simple as a dead battery or needing a new remote.

Does the wall switch work?

Alternatively, if your garage door opens and closes when you use the remote, and not when you use the wall switch, then you know it is a problem with the wall switch. In this case, you’ll likely need to have the wall switch or switch wires replaced.

Does the door open but won’t close?

If your door opens but doesn’t close, it could be a problem with your safety sensors. Make sure your sensors are in alignment. If there are in alignment, they may need to be replaced.

Does the trolley carriage move, but not the door?

If the trolley carriage moves but the door won’t open, there is probably a problem with your trolley carriage.

This troubleshooting guide, of course, won’t catch every possible problem with your garage door, but it is a good start. Going through these steps can help you determine whether fixing your garage door is an easy repair—and if it isn’t, you’ll at least be able to tell your garage door repair specialist what you know about the functionality of your garage door system. When in doubt, go ahead and give your garage door specialist a call. If you’re located in the state of Utah, contact us at A Plus Garage Doors at one of our many locations.
