- : Working with electricity is very dangerous — be extremely careful and, if you have any doubts, contact a professional.
- 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.
- 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.
- 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.
- Step 4: Try new batteries See if dead batteries in your remote control opener are the problem.
- Step 5: Reprogram the remote If the batteries are fine, the remote might have become deprogrammed. Consult your manual for instructions on resetting it.
- Step 6: Check beam Next, make sure the beam sensor is plugged in.
- 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.
- TIP: Cleaning the sensor every season can reduce problems.
- 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.
- 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.
- TIP: 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.
- 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.
- FACT: The overhead garage door was invented in 1921, and the first electric door opener was installed in 1926.
