Abstract
A fail-safe electronically controlled defrost system is provided for use in a frost-free refrigerator suitable for home use. The defrost cycle, in the interests of power conservation, is made subject to plural input electronic control in a circuit in which the intrinsic reliability of the defrost system is specifically designed to revert to a non-power conservation mode in the event of failure of the electronics. Compressor time, door openings and user (vacation mode) settings are typical inputs for control of the period between defrosts.
