Ceiling Fan Change Capacitor

The capacitor is the module in a fan that starts the motor on its highest speed.

Ceiling fan change capacitor.

Connect the red and blue wire and put a wire nut and electric tap and insert it in the wire connector as shown in fig below. How to replace a ceiling fan capacitor. One for starting and one for running. Be sure to open the fan.

The cfc series is a range of metallized polyester film capacitors designed expressly for ceiling fan use. A capacitor is wired in series with the start winding which becomes an auxiliary winding when the fan is running. When replacing a capacitor make sure the new capacitor has same exact uf ratings as the old capacitor and can handle same voltage or higher as. They are a self healing flat capacitor winding with polyester film dielectric.

How to replace a ceiling fan capacitor. Within a certain degree of tolerance the values of the replacement have to match the values of the original capacitor. Most fans with pull chains will have a replaceable 3 in 1 capacitor while ce. The only difficulty is finding an appropriate replacement capacitor.

Suppose there is no capacitor connected in the ceiling fan motor circuit. These motors have two coils a start and run winding. A ceiling fan without a capacitor. Ceiling fan capacitors diagnosis and replacement most ceiling fans use a type of motor known as a permanent split capacitor motor.

Replacing a capacitor is easy you simply unhook the wires and hook the new one in it s place. A capacitor is connected in series with the start winding to insert a phase shift but once the motor is up to speed it becomes an auxiliary winding. Replace a new capacitor by connecting the red live wire from ceiling fan to the first terminal of capacitor and connect the blue wire to the second terminal of capacitor. This way both the starting and running windings are connected in parallel across the single phase ac supply voltage 120v in us 230v in eu.

They are mounted in a flame retardent plastic case with an epoxy r. Next open the fan and find the capacitor it is usually located in the switch housing under the blades and above the light kit. A modern ceiling fan motor has double coils.
