Start here
A garage door that won't open is almost always one of a handful of issues. Some are quick DIY checks; others (anything involving springs or cables) should be left to a technician for safety. Here's what to look at.
The 7 usual suspects
- Broken spring — if you heard a loud bang and the door won't budge, a spring likely snapped. Don't force it. (Pro fix.)
- Dead remote battery — try the wall button; if that works, replace the remote battery. (DIY.)
- Misaligned safety sensors — the little photo-eyes near the floor. If one is bumped or dirty, the door won't close (and sometimes won't operate). (Often DIY.)
- Opener unplugged or tripped breaker — check power. (DIY.)
- Disconnected trolley — the emergency-release cord may have been pulled; the door disconnects from the opener. (DIY to re-engage.)
- Snapped cable or off-track door — if the door hangs crooked, stop and call. (Pro fix.)
- Worn opener gears/motor — the opener hums or clicks but nothing moves. (Pro fix.)
When to call us
If it's a spring, cable, or off-track issue — or the opener is grinding or dead — call for same-day repair. Those aren't safe or reliable DIY fixes, and forcing the door makes them worse.
Frequently Asked Questions
My door opens a few inches then stops — why?
Often a broken spring or the opener's force limit kicking in because the door is out of balance. It usually needs a spring or adjustment.
The wall button works but the remote doesn't — what's wrong?
Almost always a dead remote battery or a remote that needs reprogramming. Easy to fix.
