Thermador Range vent hood motor is loud or noisy
When a Thermador range vent hood motor is loud or noisy, the most likely cause is worn bearings in the exhaust fan motor. Turn off power to the hood, then check whether the motor shaft moves back and forth. The shaft should not have any play. If it moves even slightly, the exhaust fan motor, fan motor, blower motor, or vent fan motor bearings are worn. Older, larger motors may have oil spouts, so lubricating the bearings can help the fan turn freely. If the motor cannot be lubricated or the noise continues, replace the motor. A loose or worn blower wheel is another common cause of range vent hood noise. Check that the wheel is tight on the motor shaft and is not scraping the fan housing. A worn or loose fan blade can cause the same problem. These checks can help pinpoint the source of an oven fan noise or range hood motor noise before you order parts. Enter your Thermador range vent hood model number to find the exact replacement motor, blower wheel, or fan blade for your appliance.
01 - Thermador 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.

The blower wheel might be worn out and loose on the motor shaft causing it scrape on the fan housing.
