Why do I have to push start my fan?

Answer: Since you can start the motor with a little push using a coat hanger I would think this might be a motor run capacitor problem, a motor winding problem or the motor bearings are tight. The motor winding problem and the motor bearing problem would require a new motor.

What causes standing fan not to rotate?

A dried out or sticky pin is one of the most common reasons for blades to stop spinning. If they spin easily and there’s no resistance, try turning your fan on and see if the pin spins. If it doesn’t, the problem isn’t the pin and there is probably a short in the motor.

Why does my ceiling fan take so long to start?

Ceiling fans that operate at speeds slower than normal can have one of four problems. Two of these issues are mechanical: loss of bearing lubrication and poor blade balance. The other two are electrical: either a bad capacitor or damaged winding.

Can a fan start without capacitor?

Yes. You can run the ceiling fan without a capacitor by manually spinning the blades. When you give manual spin to the blades, the ceiling fan starts to spin in that direction. Since this manual process is cumbersome hence a capacitor is attached to the ceiling fan to make it self-starting.

What is fan capacitor?

Why Capacitor Is Used In a Fan. In simple words, the capacitor creates a magnetic flux (torque) which makes the fan rotate. Generally, two capacitors in parallel series are used in the ceiling fan. The motor is known as “two value capacitor run motor” or “permanent split capacitor motor”.

What causes a standing fan to rotate?

Each fan uses a motor within the fan’s housing behind the spinning blades. The motor begins rotating when the on switch activates, causing the attached blades to spin as well. The oscillating feature also uses a motor attached to the main rotating blade motor. Water and moisture should not enter either of the motors.

How do I know if my ceiling fan capacitor is bad?

The capacitor is usually a black box inside the switch housing of the fan. If the case appears burnt or melted in any way, that is also the sign of a bad capacitor and it should be replaced. Keep in mind that there may be other components in the circuit with the defective capacitor.

How can I make my ceiling fan rotate faster?

How to Increase the Speed of a Ceiling Fan

1. Eliminate vibration in the blades.
2. Lubricate the fan’s moving parts.
3. Turn on the fan and see if basic cleaning has increased fan speed to its original settings.
4. Check the pull chain switch on the fan.
5. Check the wires where the pull chain switch is wired to the fan.

What happens if you remove a capacitor from a fan?

If we remove the capacitor from the ceiling fan, the motor creates pulsating magnetic field when supply is given. This pulsating magnetic field is unable to rotate the motor. When we add a capacitor to the motor winding, it creates a phase difference between the magnetic fields and creates rotating magnetic field.

What causes a fan motor to stop working?

If, however, the sleeve bearings are worn, or the fan motor is full of lint or other materials that act as a brake, then the motor may not have sufficient torque to start turning. Once the motor has begun to turn, the torque the motor can produce increases rather rapidly, so the fan can accelerate to speed.

How do you fix a fan that won’t turn on?

Check the connections to make sure they are sound and you don’t see any blackening, which is the sign of a loose connection. Unscrew and remove the fan canopy and make the same inspection. Most ceiling fans have a start capacitor that provides the torque necessary to get the blades turning.

How do you know if a capacitor is bad on a fan?

Humming, accompanied by a failure of the blades to turn, is a classic symptom of a failed capacitor. To check, turn on the fan so that the humming sound is audible and try turning the blades manually. If they start turning after a good push, you need to replace the capacitor.

Why do fans have such little starting torque?

These fans typically use a “shaded pole” design motor. They produce very little starting torque. If the fan is in good physical condition, very little starting torque is required, so the motor can overcome what little resistance there is and build some speed.
