Loosen the nuts just. Look in your instruction manual to find out whether the motion sensor s range of vision is 180 degrees or 270 degrees. 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. According to liftmaster issues with the safety sensor wiring typically occur because of a poor connection incorrectly connected wires or a short in the wire from a staple.

Adjust the sensor so it is pointed toward the center of your desired area. The circuit board on your garage door opener will have to be replaced if you want your light to function properly. Adjust each sensor in small. You can also disconnect the sensors altogether but doing this will prevent most garage doors from working.

Cycle the garage door. If you do not hear a click coming from the motor housing then the relay on the circuit board is bad. If they re turned on in both the sensors then there is no issue with the power supply. Luckily you can set most automatic garage doors to a manual mode to bypass the sensors.

Your outdoor sensor lights are not working or they seem less sensitive than usual. Loosen the small nuts that hold each sensor to the l brackets with a small adjustable wrench. Your motion sensor lights should work some of the time not just on certain occasions. This video takes you from my problem description to a successful repair all for under 24 00 u s.

Cleaning and adjustment remove any debris dust or cobwebs from the electric eye lenses on each sensor with a clean rag. The clicking noise you are looking for is the sound that comes from the relay on the circuit board. My liftmaster garage door stopped closing the normal way. Clear out any trees or shrubs that may be blocking the sensor.

If your sensors or garage door motor is blinking or your door doesn t close it s a sign you could have faulty sensors.
