What causes an electric fan to stop working?
Poor ventilation can cause dust and heat to get trapped inside the case of the motor. This can cause your fan to stop functioning—especially if your fan has an overheating feature that causes it to automatically shut off if it gets too hot.
What happens when power is applied to a fan shaft?
I have a small 120vac house fan motor i was working on and all of a sudden it started acting very strange. Without any power applied, the shaft turns freely by hand. When power is applied, the motor makes a noticeable hum and the shaft locks tight so it’s very hard to spin by hand.
How can I tell if my electric fan is still working?
If you don’t hear anything, put your ear up to the middle of the case behind the blades. Press the button to turn the fan off and on again, this time listening closely for the motor. If you hear it humming or buzzing, your motor is likely still functioning. Check the fan in multiple outlets.
Is it possible to repair an electric fan that is dead?
Repairing an electric fan can be tough if the problem has anything to do with the motor itself, which may be dead if the fan makes no noise when it’s turned on and the blades don’t turn at all after cleaning and oiling the pin.
What to do if your AC fan motor is bad?
If you suspect the fan motor is bad, the first thing you should check is the power to the motor and the power to the air conditioning unit. Locate the circuit breaker and ensure it hasn’t tripped. If the power is fine, check to see if there is proper voltage.
What does it mean when your car fan wont turn on?

Why are the blades on my fan not turning?
You will be able to see this without removing any additional parts. Fan blades gather a tremendous amount of dust and debris that then settles behind them, away from the force of the air. It is not unusual for the bearing that the fan blade unit turns on to become so clogged with debris that it cannot turn.
