ABSTRACT:
A defrost controller for a refrigeration system. The system includes a circuit having a programmable controller which monitors compressor demand from a thermostat and uses alternating current cycles of a line voltage to control on and off cycles for a defrost mode of the refrigeration system. An anti-short cycle feature is optionally included to inhibit compressor operation for a predetermined interval each time the compressor is disabled.
