SOLUTION

Safety sensors are not installed, connected, or wires may be cut. Inspect sensor wires for a disconnected or cut wire.

There is a short or reversed wire for the safety sensors. Inspect safety sensor wire at all staple and connection points, replace wire or correct as needed

The wires for the door control are shorted or the door control is faulty. Inspect safety sensor wire at all staple points and connection points and replace wire or correct as needed.

Safety sensors are misaligned or were momentarily obstructed. Realign both sensors to ensure both LEDs are steady and not flickering. Make sure nothing is hanging or mounted on the door that would interrupt the sensor’s path while closing.

Manually open and close the door. Check for binding or obstructions, such as a broken spring or door lock, correct as needed. Check wiring connections at travel module and at the logic board. Replace travel module if necessary.
