How to Tell if Your Ceiling Fan Capacitor is Bad

Intro

Since ceiling fans are efficient in terms of energy consumption they are the preferred choice for homeowners who have central air conditioning use them all year long. A capacitor is a vital component in the ceiling fan motor. It stores energy when the fan is in operation to enable it to run even when fan blades are not moving. Ceiling fan motors are powered by capacitors that could fail. In the following article, we'll explain the options available to you if the capacitor on the ceiling fan is no any more working.

What is a Ceiling Fan Capacitor and What Does it Do

A capacitor is a device that stores electricity and releases it during periods that are in high demand. Ceiling capacitors for fans are among the most important components that could be damaged within the ceiling fan. It's an energy storage device that is like a battery but the charge is stored by an electrical field rather than chemical substances to store energy.

Can a Ceiling Fan run without a capacitor?

The ceiling fan is a rotating electrical machine that can be employed to move air around or to rotate the other object. The capacitor in a ceiling fan is the source of energy needed to allow ceiling fans to function smoothly. If there were any capacitors present, it could be difficult to begin the ceiling fan, and it might not move at all.

How to Tell if Your Ceiling Fan Capacitor is Bad

When your ceiling fan isn't working properly, the cause is likely to be a defective capacitor. There are a few indicators that a damaged or undersized capacitor might be the reason for the problem:

  • The fan doesn't turn into motion or move at any speed.
  • The fan will start spinning when it is manually started
  • Some speeds are either slow or not functional
  • The motor is vibrating and turning with a hand, but it's not spinning.

Troubleshooting for a Faulty Ceiling Fan Capacitor

How to Tell if Your Ceiling Fan Capacitor is Bad

Examine the voltage at the terminals of the capacitor. If the voltage is within the spec and is not a problem, then it's probably a defective capacitor.

1. Find and remove the ceiling fan's capacitor (fuse box or disconnect switch). Take note that it is preferential to keep the ceiling fan running when replacing a capacitor to ensure you can see the way it functions.

2. Test the new capacitor using an electronic voltage meter.

3. Connect the wires, then switch the fan on to check the capacitor. If it is defective then you'll need to be replaced with an equivalent one that is of the same or larger size.

Steps on How to Replace the Ceiling Fan Capacitor(s)

1. Find a replacement part, and start changing the old part for the new.

2. Switch off the power at the fuse board, or take off the switch from the circuit and check for voltage before touching any wire (there usually isn't any power after shutting down).

3. Remove the old capacitor, take note of the polarity, then note how the old capacitor was wired.

4. Install the new capacitor into place then wire it according to the wires of the previous one.

5. Switch on the power at the fuse board or reconnect, and switch it back on Test the ceiling fan to confirm that the capacitor is in good working order.

Conclusion

It's crucial to be able to spot a defective capacitor so that you can repair it before it causes additional damage to what's previously been damaged. Easybom is hoping that you've found this post useful and has ignited your curiosity to learn more about the significance of ceiling capacitors for fans.
