Thermador Range vent hood fan or blower not working
If your Thermador range vent hood fan or blower is not working, listen for a humming sound and check whether the blower wheel turns freely. The most likely cause is worn shaft bearings in the exhaust fan motor, fan motor, blower motor, or vent fan motor. Some older, larger Thermador range vent hoods have oil spouts near the motor bearings. Adding oil may help the motor turn freely, but replace the motor if lubrication does not correct the problem or the motor cannot be lubricated. If the motor does not hum, inspect the blower wheel next. Grease, debris, or another obstruction can prevent the wheel from turning, and the wheel may also be rubbing against the blower housing. Turn off power to the range vent hood, then try spinning the blower wheel by hand. Clear any obstruction and check for contact with the housing. If the wheel still binds, replace the blower wheel or the blower wheel and housing assembly. For the correct Thermador replacement part, enter your range vent hood's model number to find parts that fit your specific appliance.
01 - Thermador 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 - Thermador 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.
