Ceiling Fan Motor Hums But Does Not Turn
Electrical problems are a bit more difficult to diagnose.
Ceiling fan motor hums but does not turn. You would still be able to turn the blades freely when the power is shut off. A hum in fan is generally due to the quivering of a motor and the amount of noise is based on housing blades and mounting. There is power being delivered to the motor hence the humming but the induced voltage is not turning the rotor that the fan blades are attached to. When i moved in it was winter but i tried the fan once and it worked.
Most often if the fan can be turned on but the blades don t spin only run at one speed or change speeds unexpectedly the fan t capacitor is defective or going bad. When a ceiling fan won t turn the problem could be mechanical or electrical. See how to replace a ceiling fan capacitor below. Hunter ceiling fan hums but doesn t start spinning hello i recently moved into a flat that has a newer hunter ceiling fan it s probably within 5 years old.
An example of an easy to fix mechanical problem is the failure to remove the packing tabs from your new fan but unfortunately most mechanical problems aren t so simple.
