Most Frequent Causes for Range vent hood fan or blower not working

For the most accurate results, enter your model number.


Cause 1Exhaust Fan Motor

Usually, when the blower motor hums but does not turn, it indicates that the motor shaft bearings are worn out. Some older, larger motors have oil spouts. If your motor has oil spouts, try adding oil to the motor bearings to get the fan to turn freely. If lubricating the motor bearings does not solve the problem, or if the motor can’t be lubricated, replace the exhaust fan motor.

If lubricating the motor bearings does not solve the problem, or if the motor can’t be lubricated, replace the exhaust fan motor.

Parts
Cause 5Blower Wheel and Housing

One possibility is that something is caught in the blower wheel. It is also possible that the blower wheel is rubbing against the blower housing. To determine if the blower wheel is at fault, try spinning the blower fan by hand. If the blower wheel does not spin freely, check for the blower wheel for obstructions. In addition, ensure that the blower wheel is not rubbing against the blower housing. If the blower wheel is clear of obstructions, but it still doesn’t spin freely, replace the blower wheel and housing.
