Why won't the lights on my Craftsman garage door opener come on after I have changed the light bulbs?
The lights do not come on. I have a Craftsman Model # 13953985D, serial number 454610200756 I have changed the light bulbs. I can here it click but no light comes on.
Someone needs to check the voltage at the light sockets. If you have 120 volts AC at the socket wires, the sockets are bad. If you don't have the voltage, the logic board is bad.
