How to fix an overheated fan easily

It has likely overheated if your ceiling fan starts making a strange noise or emitting heat. Ceiling fans are designed to cool a room down, not heat it up, so if this happens, it’s important to take action and fix the fan as soon as possible. We’ll show you how to fix an overheated fan quickly and easily. If the circuit breaker trips every time you turn on the fan, this could be a sign of a wiring or power supply issue. This is a common problem and should be fixed by yourself or call a professional to fix it. But there can be other problems like lousy motor, non-lubricated, dirty fan blades, unclean bushings, incorrectly sized motor, shorted motor windings extra.

Why is my fan motor overheating?

There can be a lot of reasons why your fan motor might be overheating, from a bad motor to unclean bushings. To fix the issue, it’s important to identify the cause. Some common reasons for fan motors overheating are below.

Lack of Maintenance

Ceiling fans should be inspected and cleaned regularly to ensure that they’re running smoothly and safely. If your fan isn’t getting the proper maintenance, it can lead to overheating and other problems.

Dirty fan blades

If your fan blades are dirty, they can impede the airflow through the fan. This will cause your fan motor to overheat and add additional strain to the bearings, shortening their lifespan.

Bad motor

If your fan motor is malfunctioning or defective, it will not adequately cool itself. This will cause the heat generated by the motor to transfer into the fan’s internal components. The internal components of your fan will then transfer this heat to its outer casing, trapping it inside and causing overheating.

Dirty bushings

Bushings can become dirty over time, which will cause them to wear down and increase the heat generated by the motor. If your fan is making more noise than usual, it might be a sign that your bushings need to be replaced.

Extra voltage

Take your ceiling fan down and check the wiring to ensure it is properly attached. If extra voltage enters the motor, it can cause the fan to heat the wire insulation to melt and may even start a fire.

Shortened motor windings

 Motor windings can become faulty over time, which will cause them to heat up and add additional strain to the fan. If your motor is overheating, it might need to be replaced or repaired.

How to fix an overheated fan?

how to fix an overheated fan

To fix your overheated motor, you first need to determine what is causing your ceiling fan to overheat in the first place. If you’ve ruled out all of the above possibilities and your ceiling fan continues to overheat, it might be time to replace the motor.

If you’ve identified the cause of the overheating and it’s something that can be fixed, like dirty fan blades or bushings, follow these steps.

Basic maintenance

Electrical equipment should be maintained according to a maintenance plan in order not only for them to work correctly but also preventative measures against dirt and dust accumulating inside the device, which could lead to overheating problems.

If your ceiling fan’s bearings are dirty or dry, they can cause overheating. Therefore, you should lubricate your ceiling fan’s bearings to ensure that the motor receives an adequate oil supply.

Ensure that all of your wirings are correctly attached and there are no loose connections. If your fan is spinning slowly, this could be due to a lack of electrical power. On the other hand, it could be the fault of the capacitor. Check the capacitors of your ceiling fan. If not working properly, change it; if maintaining your device doesn’t work, it might need replacement if you can’t find an authorized dealer to repair it for you.

Clean your ceiling fan blades

This is one of the easiest and most effective ways to fix an overheated fan. Cleaning your fan blades will help improve the airflow through the fan and reduce the amount of heat produced.

Motor condition

If your fan motor is the root cause of the overheating, motor windings can become short, which will cause them to overheat. If this is the case, you can repair or might need to replace the motor.

If you’ve identified the cause as a bad or incorrectly sized motor, then 

Find a replacement motor for your exact model online. If you can’t find the exact model, find a motor as close as possible.

Use pliers to remove the old motor windings.

Wind the new motor windings onto the shaft of the new motor.

Carefully replace the motor housing on top of the new motor windings.

Reassemble your ceiling fan using the new motor.

Start your ceiling fan and make sure it is working properly. 

Replace dirty bushings

Bushings can become dirty over time and will need to be replaced to fix the overheating problem, so replace the bushings if it is the cause of heating.

Check to wire

Ensure that all of your wirings are properly attached and that there’s no extra voltage entering the motor. If there is, it can be a cause of fan heating.

If you’re comfortable with repairs, you can try to fix the issue yourself. However, if you’re not comfortable, it’s best to leave the repairs to a professional.

I hope that you enjoyed it, and now you know how to fix an overheated fan. Please feel free to ask in the comments section if you have any questions. I’ll do my best to answer them as quickly as possible.
