"The opener isn't working" covers a few very different problems — no response at all, a hum with no movement, or a motor that runs but the door doesn't budge. Each points to a different fix.
Opener does nothing at all
- Check it's plugged in and the outlet has power (test with another device)
- Check the breaker/GFCI hasn't tripped
- Replace remote and wall-console batteries
- Confirm the wall switch's wire hasn't come loose at the terminal
Opener hums but the door doesn't move
This usually means the motor is trying to lift a load it can't handle — almost always a broken or badly weakened spring, not the opener itself. Running it repeatedly in this state can burn out the motor. Disconnect it and get the spring checked before trying again.
Opener runs the full cycle but the door doesn't lift
This points to the opener's drive mechanism, not the door — a stripped drive gear (common on older chain/belt openers) or a disconnected trolley. This is a legitimate opener repair or replacement, not a spring problem.
Door reverses immediately or won't close
Nearly always the safety photo-eye sensors — check they're aligned, clean, and both showing a steady light with nothing blocking the beam between them. If they're fine, the close-force or limit settings may need reprogramming.
Frequently Asked Questions
How long do garage door openers last?
Typically 10–15 years with normal use. If yours is older and needs frequent repairs, replacement is often more cost-effective than repeated part swaps.
Can I install a new opener myself?
It's possible for a handy homeowner, but incorrect force/limit settings or a poorly mounted rail are common DIY mistakes that create safety issues. Professional installation includes calibrating the safety reversal system properly.
