How do you fix a fan motor that won’t spin?
Re-oiling the pin will usually solve this problem.
- 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 do fan motors stop working?
The torque to drive the motor of your electric fan comes from the magnetic field induced in the motor coils when electricity passes through the coils. When the fan slows down and stops, it could simply be because the coils are worn out, but it’s often a burned-out capacitor.
How do you fix a fan that won’t oscillate?
How to Fix an Oscillating Fan
- Unplug the fan before any repairs are made.
- Take off the grill of the fan.
- Check the motor housing, shaft, blades and grill to see if they need to be cleaned.
- Check the set screw for any wear or damage.
- Check the motor housing and gear assembly.
Why is my fan humming but not turning?
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.
What causes a fan to stop spinning?
One of the most common reasons fans stop spinning is because of a dead capacitor. Each air conditioning system has several capacitors, including the start capacitor, which sends signals to the motor, and the run capacitor, which keeps the motor running. Capacitors can go bad over time and need to be replaced.
Can I use WD-40 on fan motor?
[ Never put WD-40 in] any electric motor, even if the rotor is stuck from filthy dried-up lubricant! It not only removes any remaining lube, but it can melt coil wires (the lightly-coated copper wires twisted up in electric motors) and cause an electrical short.
What causes an electric motor to lock up?
Stressful mechanical, environmental, and electrical operating conditions can all cause electric motor failure. Electrical failures are winding failures caused by an open contactor, bad connection, blown fuse, excessive heat, electrical overload, or broken power lines.
What causes AC fan motor to burn up?
The fan will stop circulating the air throughout your HVAC system. It most commonly occurs when the blower fan motor becomes aged or is overworked. A lack of regular maintenance is generally to blame for blower fan burnout.
Why is my fan weak?
Weak airflow is a sign of blower motor failure. This part wears out eventually, meaning its fans can no longer push adequate amount of air out the vents or through window defrosters. In other situations, air may not blow out on some speed settings at all. Ask your mechanic to check it out.
How do you know if your blower motor is bad?
You might also hear ongoing whirring noises, or noises that change or get louder if you increase the fan speed. These are all signs of problems with the blower motor. In some cases, you may even notice smoke or smells of burning while driving, in which case you should pull over immediately.
What can I do with an old fan motor?
We bet you’ll want to repurpose your old fan after you see these projects!

- Coat garment rack. Repurposing Junkie.
- Dragonfly project.
- DIY candelabra flower planter.
- Craft Your Happiness.
- Rustic farmhouse windmill blades.
- Blade attachments for hooks.
- Outdoor solar lights.
Why did my oscillating fan stop working?
Any moisture within the motor’s mechanical parts can corrode the internal bearings. Corroded bearings will eventually seize, causing fan turning failure for both the oscillating feature and blade movement.
How do I stop my fan from moving?
The blades are unbalanced.
- Clip a clothespin to the side of a blade, about halfway from the end of the blade to the center of the fan.
- Turn the fan on a low speed and see if it still wobbles. If it doesn’t, you’ve found the unbalanced blade.
- You can fix the unbalanced blade with some coins or a blade balancing kit.
