Range vent hood fan or blower not working
Is your range vent hood fan or blower not working? Listen for a hum when you turn it on. A humming motor that does not rotate usually has worn shaft bearings. Older, larger range vent hoods may have oil spouts, so lubricating the motor bearings can restore operation. If the motor cannot be lubricated or still will not turn freely, replace the exhaust fan motor, fan motor, blower motor, or vent fan motor, depending on your model. If the motor is not the problem, the blower wheel may be blocked by grease or debris, or it may be rubbing against the blower housing. Turn off power to the range vent hood, then try spinning the blower wheel by hand. It should move freely without scraping or binding. Clear any obstruction and check the housing alignment. Replace the blower wheel and housing if the wheel remains difficult to turn. These repairs can resolve a range hood fan not working, range hood blower not working, or vent hood fan not spinning problem. Enter your model number to find the exact replacement part for your specific range vent hood.
01 - Range Vent Hood Exhaust 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.

05 - Range Vent Hood Blower 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.
