Bosch Range vent hood fan or blower not working
If your Bosch range vent hood fan or blower is not working, start by checking whether the blower motor hums without turning. This usually points to worn motor shaft bearings, the most likely cause of a vent hood fan not working. Older, larger Bosch range vent hoods may have oil spouts on the exhaust fan motor. Add oil to the motor bearings if applicable, then check whether the fan turns freely. If lubrication does not help, or the motor cannot be lubricated, replace the exhaust fan motor, fan motor, or blower motor. If the motor does not appear to be the problem, inspect the blower wheel and housing. Grease, debris, or another obstruction can stop the blower wheel, and the wheel may also rub against the housing. Turn off power to the Bosch range vent hood, then try spinning the blower wheel by hand. Clear any obstruction and make sure the wheel spins freely. Replace the blower wheel and housing if it remains damaged or binds. Enter your Bosch range vent hood model number to find the exact replacement part for your specific appliance.

If your motor has oil spouts, try adding oil to the motor bearings to get the fan to turn freely.

05 - Bosch 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.
