A defrost control system is provided for initiating one or more (defrost) timing cycles each at a preselected different time and for terminating the cycles at the end of their respective predetermined (defrost) periods. The unit generally includes a solid-state, microprocessor based, programmable twenty-four hour timer, and a display panel having an electrooptical digital time display and two sets of defrost status/program indicators. The two sets of defrost indicators are separately or concurrently activated to visually present a display indicative of a plurality of program and operating status events, for example, the occurrence of an automatic or manual defrost initiation.
