Opener Not Working? Check These Six Things, In This Order

1. Is it getting power?

Look for the light on the opener unit or press the wall button. Garage outlets are often on a GFCI circuit — the same one that protects a bathroom or an outdoor outlet — and a tripped GFCI two rooms away will kill the opener dead. Check the outlet with a phone charger, and check the GFCI reset buttons in the garage and bathrooms before anything else.

2. Remote batteries — and the second remote test

Swap in a fresh battery. Then test the wall button: if the wall button works and the remote doesn't, the opener is fine and the problem is the remote, its battery, or its programming. Note that some LED bulbs screwed into the opener can interfere with remote signals — if the remote got flaky when you changed a bulb, that's a real and common cause.

3. The safety eyes

The two small sensors at the base of the tracks, about six inches off the floor, must see each other. One gets bumped by a trash can or a broom and the door will start down, then reverse, or refuse to close while the opener light blinks. Check that both eyes are lit and pointing at each other, and wipe the lenses — mountain pollen and cobwebs count. Sun glare at certain hours can also blind an eye; if the failure only happens at one time of day, that's the clue.

4. The lock button

Many wall consoles have a lock or 'vacation' button. With it on, the remotes are locked out but the wall button still works — a pattern that sends a lot of people shopping for an opener they don't need. Look for a lock light on the console and switch it off.

5. The red emergency cord

If someone pulled the red release cord — or it snagged on a roof rack — the door is disconnected from the opener. The opener will run and the door won't move. With the door fully closed, pull the cord toward the door to re-engage, then run the opener. Only do this with the door down: if a spring is broken, a disconnected door can fall.

6. When to stop and call

• The opener hums but nothing moves, and the door feels extremely heavy to lift a few inches by hand — suspect a broken spring, not the opener. Stop.
• Grinding noises, a burning smell, or a chain/belt hanging loose.
• The door starts down and slams, or falls faster than it should.
• Anything involving the springs or cables — those are under high tension and are never homeowner work.
