Ceiling Fan Speed Control Capacitor

When a ceiling fan capacitor goes bad the fan may not work at all.

Ceiling fan speed control capacitor. To save space quite often capacitors that contain more than one value will often be used. Multi speed operation may also be erratic and some speeds 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 about 10x the value which just barely allows it to start.

This video will give some insight into replacing the capacitor in a ceiling fan. For ceiling fan speed controlling we use mostly two methods in which on is by using speed control using three or five wire capacitor. Check to make sure your ceiling fan s motor isn t getting too hot.

Replace the ceiling fan capacitor. For instance when you switch from medium to high on a solid state fan the speed control mechanism increases the power of the motor. If you ever face a problem with the ceiling fan such as humming noise slow speed not running the fan or fan light kit is working but fan has been stopped even with proper power supply then you are the right forum as one of the most common reason is a bad or blown capacitor instead of faulty internal windings power supply failure or.

Two wire capacitors are easy as they only contain one capacitance value. Capacitor values are measured in microfarads uf ex. To do this allow your fan to run for about 10 minutes then turn the fan off.

Suppose there is no capacitor connected in the ceiling fan motor circuit. 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. Solid state controls change the level of power in the fan motor to control the speed 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.
