Fan control receiver
If your ceiling fan has a control system with a receiver, a defective receiver can create a humming noise. Make sure you are using a control system that is compatible with your particular fan model – refer to your fan manual to verify compatibility.
Lights on dimmer switches
Light dimmer switches often create an electrical hum sound. We suggest using a Hunter control system to dim your ceiling fan lights.
If you've tracked the buzzing to an outlet or wiring, arrange for a certified, professional electrician to repair it.
An electrical hum can come out of a circuit breaker if it is overloaded with current and not shutting off as it's meant to. Please contact a certified, professional electrician to investigate and repair the cause of the buzzing.
A defective motor can potentially cause buzzing. Once you have ruled out the other potential sources, contact the manufacturer’s customer service department to help troubleshoot a potential motor issue. For Hunter ceiling fans, reach out to our customer service team and make sure you have your ceiling fan model number handy.
