Abstract
Apparatus and method for defrosting a refrigerator in an operator actuated vacation mode wherein, after the operator actuation, the next defrost cycle is executed in accordance with the previously existing schedule in the normal defrost mode. If the time duration to execute the next defrost cycle is greater than a predetermined time period, the controller continues to defrost in the normal mode. However, if the next of a subsequent defrost cycle is executed in a relatively short time duration, the interval between defrost is significantly increased to a fixed interval of compressor run time hours.
