chevron_rightFrequently Asked Questions
Why does my ceiling fan hum but not move?expand_more
The humming sound means electricity is reaching the motor, but it lacks the power to turn. This is almost always caused by a blown start capacitor or motor bearings that are completely seized with dirt and old grease.
How do I oil a ceiling fan motor?expand_more
First, find the oil hole (usually on the top of the motor housing near the downrod). Use 10-15-20 weight non-detergent motor oil. Never use WD-40, as it will dry out the bearings further.
If my fan motor is burnt out, can I fix it?expand_more
If the copper windings inside the motor are visibly charred or smell like burnt ozone, the motor is dead. In this case, it is cheaper and safer to replace the entire ceiling fan.
