"The opener won't work" covers a lot of different problems, and you can narrow it down in a couple of minutes without any tools. The trick is to figure out how much of the system is actually dead.
Narrow it down
- Only the remote fails, wall button works → almost always a remote battery or a re-pair. Cheapest fix, usually DIY.
- Nothing responds — remote and wall button both dead → check power first: the outlet, the breaker, and that the opener is plugged in. If power's fine, it's likely the logic board or motor.
- Opener hums or the light blinks but the door won't close → look at the safety sensors near the floor. A bumped bracket or a blocked beam makes the door refuse to close and reverse. Realigning them is often a DIY win.
- Motor runs but the door doesn't move → the trolley may be disconnected (the pull cord), or the drive belt/chain or gear is worn.
What's safe to try — and what isn't
Safe: new remote battery, re-pairing the remote, cleaning and realigning the photo-eye sensors, confirming power, and checking whether the manual release cord got pulled. Not worth DIY: opening up the motor housing, replacing the logic board, or anything where the door itself feels heavy or off-balance — that points to a spring or cable, not the opener.
If the simple checks don't bring it back, describe what you're seeing — which parts respond, which don't — and a pro can pinpoint it fast.

Common questions
- Why does my garage door opener hum but not open?
- A humming motor that won't move the door often means a broken spring, a disconnected trolley, or a worn gear. If the door also feels heavy by hand, suspect the spring — and don't force it.
- My remote stopped working but the wall button works — why?
- That almost always points to the remote itself: a dead battery or lost pairing. Replace the battery and re-pair it to the opener before assuming anything's wrong with the motor.
- How do I know if it's the opener or the door?
- If the motor runs but the door won't move, or the door feels very heavy to lift by hand, the problem is usually the door's springs or cables, not the opener. A pro can confirm which in person.
