Your Thermador hood isn’t immune to most issues other hoods often suffer from. One of the top troubles is related to the 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. The other 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. Ensure that the fan blade turns freely. If the fan does not turn freely, check to see if the fan blade is rubbing against the blower housing. Inspect the fan blade for damage. If the fan blade is damaged, replace it. Remember that all appliances require correct maintenance and timely assistance in case of a breakdown. Schedule professional diagnostic and prevent troubleshooting.
