Broan Range vent hood motor is loud or noisy
Is your Broan range vent hood motor loud or noisy? The exhaust fan motor is the most likely cause. Worn motor bearings can let the motor shaft move from side to side, creating a humming, grinding, or rattling sound. Turn off power, then gently wiggle the shaft. It should not move. Older Broan motors may have oil spouts, so lubricating the motor bearings can help the fan turn freely. If the bearings are worn, the motor cannot be lubricated, or the noise continues, replace the exhaust fan motor, fan motor, blower motor, or vent fan motor. A loose or worn blower wheel is another common cause of range hood fan noise. Check that the wheel is tight on the motor shaft and is not scraping the fan housing. The fan blade can develop the same problem if it slips or becomes loose. This troubleshooting guidance applies to Broan range vent hoods, including noisy range hood fans and exhaust fan motors. Enter your model number to find the exact replacement motor, blower wheel, or fan blade for your specific Broan range vent hood.
01 - Broan 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.
