My Hampton bay ceiling fan quit working. Intermitantly and without any activation from the wall switch or pull chain it will start on its own for a few seconds then stop. There is a slight hum from the motor whenever this happens what are the possible causes and solutions?

Thanks

Sounds like a switch going bad or a loose connection in the circuit. If the fan is a few years old it could be internal as well... Check the switch, check the wiring, (splices and connections), rule out what you can...
You will need a voltage meter to test things.

Why does no one use the troubleshooting guides anymore?
