Motion Sensor Garage Door Not Working

My liftmaster garage door stopped closing the normal way.

Motion sensor garage door not working. If you do not hear a click coming from the motor housing then the relay on the circuit board is bad. Luckily you can set most automatic garage doors to a manual mode to bypass the sensors. Cleaning and adjustment remove any debris dust or cobwebs from the electric eye lenses on each sensor with a clean rag. If they re turned on in both the sensors then there is no issue with the power supply.

Your outdoor sensor lights are not working or they seem less sensitive than usual. The sensors have to be aligned with each other and also have to be connected correctly to the garage door system in order to work. If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. Cycle the garage door.

This video takes you from my problem description to a successful repair all for under 24 00 u s. The clicking noise you are looking for is the sound that comes from the relay on the circuit board. Adjust each sensor in small. Your motion sensor lights should work some of the time not just on certain occasions.

Whether you re using motion sensing flood lights or security spotlights a quick reset is the first step when troubleshooting issues. If your sensors or garage door motor is blinking or your door doesn t close it s a sign you could have faulty sensors. Clear out any trees or shrubs that may be blocking the sensor. Look in your instruction manual to find out whether the motion sensor s range of vision is 180 degrees or 270 degrees.

A common cause of a malfunctioning garage door sensor is lack of power supply. Loosen the nuts just. You can also disconnect the sensors altogether but doing this will prevent most garage doors from working. Look for small led lights on the sensors.

Adjust the sensor so it is pointed toward the center of your desired area.
