Many opener problems have simple causes. Work through these checks in order — they're all safe for a homeowner to try. If none of them solve it, the problem is likely electrical or mechanical and needs a pro.
1. Check the power
Is the opener plugged in? Has the GFCI outlet or breaker tripped? Garage outlets trip more often than you'd think, especially after storms. Reset the breaker or GFCI and test again.
2. Remote not working
- Replace the remote battery — this fixes the majority of "dead remote" cases.
- Reprogram the remote to the opener (hold the Learn button on the motor unit, then press the remote button).
- Check for interference: LED bulbs in the opener, nearby radio devices, or a neighbor's new opener on the same frequency can all interfere. Try the remote from different distances.
3. Wall control works but remotes don't
This points to the receiver or remote programming rather than the motor. Try reprogramming; if multiple remotes all fail, the logic board's receiver section may have failed — a pro repair.
4. Door reverses instead of closing
This is the safety sensors doing their job — or misfiring:
- Wipe both sensor lenses clean and check that their indicator lights are solid (not blinking).
- Make sure the sensors face each other directly — a bumped bracket misaligns them.
- Check for obstructions: cobwebs, leaves, or even bright sunlight hitting a sensor can trigger reversal.
- If the door still reverses with clear, aligned sensors, the close-force or limit settings may need adjustment — call a pro rather than overriding safety settings.
5. Motor runs but the door doesn't move
Stop and call a professional. This usually means a stripped drive gear or a broken spring — running the motor further can damage the unit. Do not keep pressing the button.
6. Excessive noise
Grinding often means a worn chain or dry rail; banging can mean loose hardware or failing rollers. Lubricate the rail and rollers with proper garage door lubricant (not WD-40). If noise persists, have a pro inspect before something fails.
7. Keypad not working
Replace the keypad battery and reprogram the PIN. If the keypad is 10+ years old, the membrane buttons themselves wear out — replacement keypads are inexpensive, and a pro can pair one in minutes.
