Abstract
An over-voltage control device for a clothes dryer including an electrical heater coupled to an alternating current power supply is provided. The device includes a switch device adapted to connect and disconnect the power supply from the heater, and a micro-controller coupled to the switch device. The switch device is responsive to said micro-controller, and the micro-controller is configured to operate said switch to maintain an effective heater voltage below a predetermined threshold to avoid tripping of a circuit breaker.
