Ceiling Fan Speed Control Capacitor

Our ceiling fan was not turning at full speed when selecting high speed the.

Ceiling fan speed control capacitor.

The 3 wire is normally used to control the speeds of the fan. 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. This video will give some insight into replacing the capacitor in a ceiling fan. 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.

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. Multi speed operation may also be erratic and some speeds may not work at all. The 4 wire fan capacitor is normally used as a combo start and speed but can be for speed only. Check to make sure your ceiling fan s motor isn t getting too hot.

The way in which your fan s speed control actually works depends upon whether it has a capacitor or solid state control. For instance when you switch from medium to high on a solid state fan the speed control mechanism increases the power of the. A ceiling fan without a capacitor. When a ceiling fan capacitor goes bad the fan may not work at all.

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 2 wire ceiling fan capacitor is normally used as a start capacitor. Replace the ceiling fan capacitor.

Solid state controls change the level of power in the fan motor to control the speed of the fan.
