Universal Range vent hood fan or blower not working

When your universal range vent hood fan or blower is not working, start with the exhaust fan motor or blower motor. If the motor hums but the fan does not turn, worn motor shaft bearings are the most likely cause. Older, larger motors may have oil spouts, so lubricating the motor bearings can help the shaft turn freely. If the motor cannot be lubricated or still will not run, replace the exhaust fan motor, fan motor, or blower motor. If the motor is not the problem, check the blower wheel and housing. Grease, debris, or another obstruction can stop the blower wheel, and the wheel may also rub against the housing. Turn off power to the range hood, then try spinning the blower wheel by hand. It should turn freely. Clear any obstruction and check for rubbing. If it remains difficult to turn, the motor bearings are worn and the motor should be replaced. These steps address common range hood fan not working and vent hood blower problems. Enter your model number to find the exact replacement part for your specific range vent hood.

01 - Universal 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 - Universal 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.
