I have a ceiling fan in my living room, which has sockets for 3 candelabra bulbs. When there were incandescent bulbs in it, it worked perfectly. I replaced the incandescent bulbs with 3 LED bulbs. 2 of the bulbs work fine. I noticed one bulb would go visibly dimmer than the others at random. It would stay that way for a while, then randomly get bright again. This happened over a course of several months, until the bulb just died. I assumed it was just a defective bulb. However, I replaced the bulb and the same thing is happening. It could be wiring, but I dont know why it would be so inconsistent. Additionally, the fan is never on. So its not as if the vibrations of the fan are moving the wires.
Im not sure where to begin troubleshooting. Ideas?
