Linear garage door opener sensor problems.

When the led or the light bulb on your linear garage door opener flashes three times it means the problem is from the safety sensor. If the circuit breaker or gfci is tripping repeatedly it s a sign that there is a short circuit somewhere in the system possibly even the garage door opener itself. When this happens the door will reverse when closing. This video is for a linear garage door opener.

A common cause of a malfunctioning garage door sensor is lack of power supply. Safety sensors sit about six inches off the ground by the garage door tracks and are always getting hit or obstructed in a busy home. The most common problem with garage door openers is safety sensor misalignment. Look for small led lights on the sensors.

If they re turned on in both the sensors then there is no issue with the power supply. Two types of accidental obstructions can cause the safety sensor to prevent a garage door from closing. Two things can cause this as well first there is an obstruction in the doorway and secondly safety sensors are misaligned. Finally it s possible the garage door opener s motor has burned out and isn t operating at all.

This is a problem that will require you or a service person to replace it.
