Ceiling Fan Speed Control Capacitor

The 4 wire fan capacitor is normally used as a combo start and speed but can be for speed only.

Ceiling fan speed control capacitor.

Suppose there is no capacitor connected in the ceiling fan motor circuit. Replace the ceiling fan capacitor. Ceiling fan speed control switches are usually wired such that the switching sequence runs off high medium low off so that the fan starts up with the full speed capacitance to get it going. Multi speed operation may also be erratic and some speeds may not work at all.

When a ceiling fan capacitor goes bad the fan may not work at all. In the above ceiling fan speed control wiring diagram i shown the main winding running winding and i connect run wire of motor to the speed control switch and you can see it in above diagram that connection of run wire of motor in switch l point and and 1 and 2 for capacitor. This video will give some insight into replacing the capacitor in a ceiling fan. Check to make sure your ceiling fan s motor isn t getting too hot.

A ceiling fan without a capacitor. The way in which your fan s speed control actually works depends upon whether it has a capacitor or solid state control. Solid state controls change the level of power in the fan motor to control the speed of the fan.

The 2 wire ceiling fan capacitor is normally used as a start capacitor. To do this allow your fan to run for about 10 minutes then turn the fan off. Our ceiling fan was not turning at full speed when selecting high speed the. You ll probably need to do a bit of experimenting with capacitor values but a rough guess would be to choose a full speed total capacitance of.

The 5 wire and 6 wire will normally be used for both start and speed on the ceiling fan.
