Abstract: In a clothes dryer, an integrated circuit control which governs the operation of an alternating current relay through a phase shift circuit for shifting the point of operation of the relay 180* to provide relay operation at reverse line polarities to prevent relay contact erosion. The drive motor relay is the most active and therefore the one relay precisely controlled, although other relays are also controlled by the circuit.
