Common Fixes For an Automatic Garage Door

When an automatic garage door is malfunctioning, you may be able to fix the problem on your own; some problems are relatively simple to fix. Even if you can't fix the garage door problem yourself, you may want to note a few details to a repair person when they arrive so they know what you've tried and where to start looking for a problem. Note a few common fixes for automatic garage doors that you might check or consider before you call for repairs.

1. If the door closes fully and then opens again

Garage door openers usually have what is called a close limit setting. This tells the garage door how far down it needs to go to actually be closed. If this setting is misaligned, the garage door may think that it has hit something in its path when it tries to close, and then it will open again so you can clear what it reads as an obstruction. Your garage door owner's manual should tell you how to adjust these settings so your garage door knows that it's actually closed when it hits the ground.

2. Transmitter batteries and power

You may know to check the batteries in your remote control when the door doesn't function, but remember that the transmitter on the wall of your garage may need batteries as well. Many homeowners forget about checking the batteries to this piece when the door doesn't work. You also want to check the wiring and connectors to the housing unit at the top of the garage, if they're exposed. Note if there are loose connectors that need tightening, so the unit is actually getting power.

3. The motor runs but the door doesn't move

Many automatic garage doors have a lock that you can engage when you're working on the garage door to ensure that it doesn't close for any reason. If you can hear the garage door motor working, but the door doesn't move, you may have inadvertently engaged this lock. Check your garage door owner's manual if you aren't sure the location of this lock and note if you've engaged it so you can switch it off.

4. New garage door closes too quickly

If you've had a new door installed but didn't change the springs or the tension of the springs, your new door may be too heavy for the springs to manage. Putting a new steel door on springs meant for a lightweight wood or aluminum door can cause the door to close very quickly, as the springs cannot control its speed. If your new door closes too quickly, talk to a technician about simply adjusting the springs.
