Direct answers to common questions
Why is my garage door opener not working?
The cause may be power, controls, lock mode, remotes, photo-eye sensors, travel settings, the trolley, or the opener itself. A broken spring, cable, track, or unbalanced door can look like an opener failure, so stop operating a crooked, hanging, unusually heavy, or falling door.
Checks that avoid door hardware
Power and controls
Confirm the opener has power, the wall station is not in vacation or lock mode, and remote batteries and settings have not changed.
Photo-eye sensors
Look for blocked lenses, obvious dirt, loose mounting, or indicator-light changes without bypassing or rewiring the safety system.
Door position and sound
Note whether the motor runs, hums, clicks, moves briefly, reverses, or operates the trolley while the door remains still.
Manual release status
From a safe position, observe whether the emergency-release mechanism appears disconnected; do not pull it when a raised door may fall.
Stop operating the door when
- The door is crooked, off track, hanging, unusually heavy, or supported by damaged cables or hardware.
- A spring is broken or separated, a cable is loose, or a bracket or track is pulling away.
- The opener repeatedly strains, the rail flexes, or the door drops, slams, or will not stay in position.
- Smoke, sparking, burning odor, exposed wiring, or repeated breaker trips are present.
An opener is not designed to lift a door with a broken counterbalance system. Repeated operation can add damage or create a falling-door hazard.
Information for the technician
- Opener brand, model, approximate age, and visible error or light pattern.
- Whether wall control, remotes, keypad, app, lights, and sensors respond.
- The exact point where movement stops or reverses and any sound at that moment.
- Recent power outages, impacts, door work, remote programming, or changes in balance and noise.
