Range vent hood motor is loud or noisy
Is your range vent hood motor loud or noisy? Worn motor bearings are the most likely cause. Turn off power to the range vent hood, then check the exhaust fan motor, fan motor, blower motor, or vent fan motor shaft for side-to-side movement. The shaft should not move, even slightly. If the motor has oil spouts, lubricate the bearings and check whether the fan turns freely. Replace the motor if lubrication does not correct the noise or the bearings cannot be serviced. A loose or worn blower wheel is the next likely problem. The wheel can slip on the motor shaft and scrape against the fan housing, creating a rattling or grinding sound. Check that it is tight and replace it if damaged. A loose or worn fan blade can cause the same range hood making noise symptom, so inspect the blade for shaft movement or contact with the housing. Before ordering a replacement exhaust fan motor, blower motor, blower wheel, or fan blade, enter your model number to find the exact part for your range vent hood.
01 - Range Vent Hood Exhaust Fan Motor
The exhaust fan motor bearings might be worn out. To determine if the motor bearings are worn out, try wiggling the motor shaft back and forth. The motor shaft should not move at all. If the motor shaft moves even by a slight amount, the motor 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
The blower wheel might be worn out and loose on the motor shaft causing it scrape on the fan housing. Check to make sure the wheel is tight on the motor shaft and has not slipped on the shaft causing it to contact the fan housing. If the blower wheel is loose on the motor shaft it should be replaced.
Highly Likely
06 - Range Vent Hood Fan Blade
The fan blade might be worn out and loose on the motor shaft causing it scrape on the fan housing. Check to make sure the blade is tight on the motor shaft and has not slipped on the shaft causing it to contact the fan housing. If the fan blade is loose on the motor shaft it should be replaced.
