Fan Does Not Work On All Settings. One is the regular cooling system fan and it is operated by a temperature. A resistor resists the flow of electric energy, turning it into heat energy. Fan blades attached to the underside create a low-pressure condition which, when compared to the outside environment, manifests itself as suction. An inline exhaust fan is best defined as a fan that is mounted inline (inside or connected to ducting) that is used for extraction purposes. 1 Single Phase Induction Motor Control Theory Single-phase induction motors are th e most used. If the cooling fan motors burn out or fail, the cooling fans will be disabled. A motor capacitor , such as a start are only applicable for the short motor starting time.
