Start with the safety sensor path
Remove objects from the opening, clean both photo-eye lenses, and look for a bumped bracket or damaged wire. Both sensor indicators should be stable according to the opener manufacturer’s design.
Mechanical resistance can also cause reversal
A bent track, worn roller, dragging seal, damaged panel, loose hardware, or cable issue can make the opener detect excess resistance. Increasing force is not a proper fix for a binding door.
Travel and limit settings
If the opener believes the floor is farther away than it is, the door may hit the ground and reverse. If the close travel is too short, it may stop above the floor. Settings should be adjusted only after mechanical operation and sensors are verified.
Securing the garage safely
Some openers allow constant-pressure closing from the wall control when the sensor circuit is faulted. This is a temporary supervised function, not a repair. Do not tape sensors together or remove them from the opening.
Frequently asked questions
Door Won’t Close FAQ
Why does my garage door close and then reopen?
The opener may be detecting the floor too early, sensing an obstruction, responding to misaligned sensors, or encountering mechanical resistance.
Why do the opener lights blink?
Blinking patterns often indicate a sensor or diagnostic fault. The meaning varies by brand and model.
Can I bypass garage door sensors?
The safety system should not be permanently bypassed. Repair the alignment, wiring, bracket, or failed component instead.
