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.

The method of controlling the interval between refrigerator defrost cycles in an operator actuated mode wherein, in the normal mode of operation, the duration of a defrost cycle is measured and then the interval to the next defrost cycle is determined in accordance with an inverse relationship to the measured duration, comprising the steps of: initiating the next defrost cycle according to the scheduled interval as determined in the normal mode of operation before the operator actuation of the operator actuated mode; initiating defrost cycles in accordance with the normal mode of operation if the measured duration of the next defrost cycle is longer than a predetermined time period; and initiating defrost cycles at a fixed interval greater than intervals in the normal mode if the next or a subsequent defrost cycle is shorter than a predetermined time period.
