The invention is directed to an ice and snow melting system. At least one sensor is provided, with each sensor being configured for sensing a temperature or moisture associated with an ambient environment and providing a signal indicative thereof. A heater for melting the ice and snow includes at least two electrical conductors associated therewith. An automatic controller is connected to the at least one sensor, and includes a ground fault circuit interrupter in communication with at least two of the electrical conductors associated with the heater. The ground fault circuit interrupter detects a ground fault condition associated with the heater and provides a signal indicative thereof. The controller selectively controls operation of the heater dependent upon the sensor signal and/or the ground fault circuit interrupter signal.
