A noisy ceiling fan can keep you awake at night. There are several possible causes, including some that can damage your ceiling if left for too long! The specific sound can be a good indication of the cause.
Humming could be related to dimmer controls. Some fans have dimmer controls to control fan speed, but many were not designed for the purpose. Your dimmer control should be swapped with standard speed controls.
Alternatively, your remote could be the source of humming. If your fan has a bad receiver that doesn’t get a strong signal from the remote, you will likely experience humming. If this is the case, you can have the receiver removed and connect your fan directly to the power source.
Bad capacitors are another reason for humming. This can be fixed by putting in a new switch or capacitor. If this doesn’t fix it, it could be a low voltage problem. This often occurs when several fans are connected to one circuit.
If you hear a rattling noise, some loose screws are the likely culprit. These can be a danger to your home and family if they become dislodged while the fan is on.
Your fan noise may be amplified when it is mounted directly into the ceiling joist. To avoid this noise, your fan should be mounted with approved hangers. This isolates the fan from the ceiling joist and reduces the sound.
If your ceiling fan is making any sort of sizzling noises, or even if it just smells funny when operating, it’s important you have a licensed electrician out to have a look at it. Your ceiling fan could be a fire risk.
