Signs to watch for
Different faults can look alike. These clues can help you explain the problem, but a technician needs to inspect the door to identify the cause.
- The wall button works but the remote does not.
- The door reverses before it reaches the floor.
- The motor runs but the door does not move.
What happens next
Check that the opener has power, replace a remote battery if needed, and see whether the safety sensors are obstructed. Do not bypass sensors. If a spring is broken or the door is crooked, stop using the opener and request door service instead.
Safety note: Never bypass the safety sensors or adjust springs to solve an opener problem.
Questions people ask
Why does my garage door close then reverse?
An obstruction or misaligned safety sensor is one possible cause. Clear the doorway and check the sensor lights without bypassing the system. If the issue persists, have it inspected.
Can a broken spring make the opener seem broken?
Yes. A failed spring leaves much more weight for the opener to lift. Stop using the opener if the door is unusually heavy.
