Electric garage doors are a great convenience — until, of course, they break. The bad news: a dozen things could be to blame. The good news: many are easy to fix yourself.

You Will Need

  • Batteries for your remote control
  • Your owner's manual
  • A wet cloth
  • An electrician (optional)

Working with electricity is very dangerous — be extremely careful and, if you have any doubts, contact a professional.

How To Repair a Garage Door Opener: Check plug

Step 1: Check plug

See if the opener’s cord is plugged into a working outlet. Of course it’s a “duh” — but it’s also the most common reason electric garage doors don’t open.

How To Repair a Garage Door Opener: See if lock is on

Step 2: See if lock is on

Now check the second most-common stupid reason that an electric garage door won’t open—the owner inadvertently activated the “lock” feature. Many people aren’t even aware of this feature—consult your owner’s manual.

How To Repair a Garage Door Opener: Turn off and on

Step 3: Turn off and on

Try unplugging the garage door opener and then plugging it in again; this sometimes does the trick by resetting the sensors.

How To Repair a Garage Door Opener: Try new batteries

Step 4: Try new batteries

See if dead batteries in your remote control opener are the problem.

How To Repair a Garage Door Opener: Reprogram the remote

Step 5: Reprogram the remote

If the batteries are fine, the remote might have become deprogrammed. Consult your manual for instructions on resetting it.

How To Repair a Garage Door Opener: Check beam

Step 6: Check beam

Next, make sure the beam sensor is plugged in.

How To Repair a Garage Door Opener: Clean the sensor

Step 7: Clean the sensor

Clean the sensor’s eyes—usually located in front of the on/off button—with a wet cloth. When these eyes get dusty, it can block the signal that turns on the motor.

Cleaning the sensor every season can reduce problems.

How To Repair a Garage Door Opener: Check the chain

Step 8: Check the chain

Next, check to see if the chain is broken or loose. Unfortunately, if it needs to be tightened or replaced, you’ll need to contact an electrician.

How To Repair a Garage Door Opener: Open manually

Step 9: Open manually

If none of your quick fixes have worked, pull the red release cord to free the door so that it can be opened and closed manually.

Consult your owner’s manual — older systems may not have a red release cord. They can be opened by pulling down a handle or a spring-loaded clip, or by unbolting the arm between the door and opener.

How To Repair a Garage Door Opener: Get help

Step 10: Get help

Operate your door by hand until you can have the unit fixed. Contact either an electrician or the service department of the store where you bought your unit.

The overhead garage door was invented in 1921, and the first electric door opener was installed in 1926.
