The Bosch 00652270 Range Fan Motor effectively provides air circulation to dispel smoke, odors, and heat out of the kitchen. It is used to propel the fan blades and it works by sucking air and releasing it through the exhaust system to ensure that the cooking area is clean. This motor also help to maintain a steady flow of air, avoiding the accumulation of grease and other airborne particles, as well as heat. Fresh air reduces the amount of heat and stress on the inside of the appliance, and is a beneficial replacement part to increase the longevity of the appliance.
