I installed it and the lights are on, but the 41a5034 Garage Door sensors are not working properly. What should I do?

You need to see if the transmitter and receiver are at the same level. It needs to be at the same level for the receiver to receive the signal from the transmitter. If the sensor itself is faulty. We can replace it with a new one for you.
