Garage door starts to close then reverses and opens fully; lights flash.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Down travel set too short, door hitting obstruction, tight or damaged rollers, misaligned tracks

Safety: Ensure nothing is under the door before testing.

Inspect for obstructions: Check tracks and floor for objects or buildup that the door may be hitting.
Check door hardware: Look for bent tracks, broken rollers, or loose hinges. Lubricate moving parts.
Adjust down travel: Increase the down travel slightly using the travel adjustment screws or electronic settings so the door fully reaches the floor without excessive force.
Re-test safety reversal: Place a 2x4 under the door and close. The door must reverse on contact.
