What causes a fan motor to slow down?

The capacitor on an electric fan is called a run capacitor, as opposed to a start capacitor that gives the needed extra torque for some motors to start. When the capacitor burns out, the electric current through the coil is too steady to generate torque, and the fan slows down and stops.

Why does my fan sometimes speed up and slow 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.

Why would a ceiling fan slow down?

The reason a ceiling fan is spinning slowly is almost always the result of dirty or damaged ball bearings. Moreover, the bearings become less round as they grind along. Even at the top speed setting, with enough friction, the fan blades move slowly or not at all, and the motor may even burn itself out.

Why does my ceiling fan only have 1 speed?

The ceiling fan capacitor decides the amount of the power to be delivered to the motor. When the capacitor does not work, the required amount of the power will not be transferred to the motor and that might make your ceiling fan to stick on the same speed. You can change the capacitor to fix the issue.

Why is my Ceiling Fan running slower than normal?

The fan will run slower than usual or selected speeds won’t work correctly. At that point, it’s time to take your ceiling fan down and replace the capacitor. Be sure to choose the exact type capacitor that is recommended for your ceiling fan. Otherwise, the number of speed settings and control will not work properly.

How does a ceiling fan control the speed of a fan?

A ceiling fan’s wiring is integral when it comes to controlling its speed. In order to control the fan’s speed, the fan needs its own system of wires, separate from that of the lighting element.

Can a bad capacitor cause a ceiling fan to stop working?

The bad capacitor can cause speed problems. You should always inspect the capacitor whenever you experience any speed problem in your ceiling fan. As the capacitor cannot be fixed, you should try this after checking the lubrication and blades. When none of these prove effective, you can replace the capacitor.

What are the common problems with a ceiling fan?

1 Faulty Capacitor You might experience this problem especially when your ceiling fan is a few years old. This is a common issue and can be fixed without any expertise. 2 Problems in Control Box If the problem is not with the capacitor, you can inspect the control box. It might not be in working condition. 3 Motor Cap Issues
