Why does my fan keep speeding up and slowing down?
The run capacitor stores charge and delays the current momentarily, which gives the fan rotor time to turn and orient itself so that the induced magnetic force iseffective. When the capacitor burns out, the electric current through the coil is too steady to generate torque, and the fan slows down and stops.
How can you tell if a ceiling fan capacitor is bad?
The capacitor is usually a black box inside the switch housing of the fan. If the case appears burnt or melted in any way, that is also the sign of a bad capacitor and it should be replaced. Keep in mind that there may be other components in the circuit with the defective capacitor.
Does changing capacitor increase fan speed?
When you increase the capacitance, the fan motor’s voltage goes up, but the capacitor’s goes down. The fan’s speed goes up. To increase the fan speed, you need to increase theCapacitor value.

How to Increase the Speed of a Ceiling Fan
- Eliminate vibration in the blades.
- Lubricate the fan’s moving parts.
- Turn on the fan and see if basic cleaning has increased fan speed to its original settings.
- Check the pull chain switch on the fan.
- Check the wires where the pull chain switch is wired to the fan.
Why does my ceiling fan not change speeds?
It might be caused by the loss of lubrication, poor blade balance, bad capacitor, and loose screws. Lubrication is a must to maintain and boost the efficiency of your ceiling fan. You need to check the instruction manual for the lubrication.
Can a fan run without capacitor?
Yes. You can run the ceiling fan without a capacitor by manually spinning the blades. When you give manual spin to the blades, the ceiling fan starts to spin in that direction. Since this manual process is cumbersome hence a capacitor is attached to the ceiling fan to make it self-starting.
Why is my ceiling fan running slow on high?
Ceiling fans that operate at speeds slower than normal can have one of four problems. Two of these issues are mechanical: loss of bearing lubrication and poor blade balance. The other two are electrical: either a bad capacitor or damaged winding.
