What's Happening
A door that won't open is the most common emergency call we receive. The cause ranges from dead remote batteries to a snapped torsion spring — and the difference matters because some fixes take 30 seconds while others require professional equipment.
What You May Notice
- Remote and wall button both fail to activate the door
- Opener motor runs but the door doesn't move
- Door moves a few inches then stops or reverses
- No response at all — no lights, no motor sound
- Door is visibly crooked or off track
Common Causes
- Broken torsion or extension spring — the most common serious cause
- Opener disconnected from the door (emergency release pulled)
- Photo-eye sensor misalignment or obstruction breaking the safety beam
- Locked door or manual lock engaged on the track
- Opener force settings too low after spring fatigue increased door weight
The Five Systems to Check
Work through these in order — start with the simplest before assuming the worst.
Power & Remote
The opener needs electricity and a working signal from your remote or wall button.
Check the outlet, circuit breaker, remote batteries, and whether the lock button on the wall panel was accidentally engaged.
Springs
If springs are broken, the opener cannot lift the door's full weight — even a powerful motor will struggle or fail.
Look for a gap in the torsion spring above the door. If you see one, stop troubleshooting and call a professional.
Sensors
Photo-eyes at the floor level must have an uninterrupted beam. If broken, the door won't close — and some openers won't respond to open commands either.
Clean lenses with a soft cloth and verify both sensor lights are solid (not blinking).
Tracks & Rollers
Bent tracks, debris, or seized rollers physically prevent movement even with working springs and opener.
Look for obvious bends, objects in the track path, or rollers that don't spin freely.
Opener Connection
The trolley connects the opener to the door. If the emergency release cord was pulled, the opener runs but doesn't move the door.
Re-engage by pulling the release cord toward the door while the opener runs — or manually slide the trolley until it clicks into place.
Solution Options
Quick Checks (2 Minutes)
Try these before calling for service:
- Replace remote batteries and test the wall button inside the garage
- Check that the opener is plugged in and the outlet has power
- Look for the emergency release cord — re-engage if it was pulled
- Clear any objects blocking the door's path and sensor beam
- Verify the manual lock on the track isn't engaged
Signs You Need a Professional
Call a technician if:
- You see a broken spring — gap in the torsion spring or hanging extension spring
- The door is off track or visibly crooked
- The opener motor hums but the door won't budge — likely spring or track issue
- Quick checks didn't resolve the problem

Don't Force It
Repeatedly hitting the remote or trying to force a stuck door causes secondary damage — burned-out opener motors, bent tracks, and snapped cables.
Potential Risks
- Forcing an off-track door bends tracks and cables further
- Running the opener against a broken spring burns out the motor ($300+ replacement)
⚠️ Never Attempt DIY On The Following:
- ✕Don't increase opener force settings to brute-force a heavy door
- ✕Don't pry the door open with tools if it's off track
