Why won't my garage door opener light work?

Your garage door opener light may not work for several reasons that can be diagnosed step by step. The simplest cause is a burned-out bulb. Garage door openers vibrate heavily, which breaks standard incandescent filaments quickly, so try a new rough service incandescent or garage door compatible LED bulb and ensure it is screwed in tightly and the small metal tab at the bottom of the socket is making contact. Second, the light lens cover may not be fully seated. Some openers have a safety switch that disables the light if the cover is loose. Third, the opener may need a power reset. Unplug the motor unit from the ceiling outlet for 30 to 60 seconds to reset the logic board, as power surges can cause the light relay to stick in the off position. Fourth, check the wall control. A loose wire at the motor head terminals for the wall control, or a faulty light button on the wall panel, can prevent the light from turning on. Try disconnecting and reconnecting the wall control wires. Fifth, the logic board itself may have failed. The light relay on the board is a common failure point after lightning or using a bulb with too high wattage that overheats the socket. If the opener operates the door but the light never comes on even with a new bulb and reset, the light socket assembly or main circuit board likely needs replacement.
