A bypass and monitoring circuit is described for use with a refrigeration system having means to sense a need to initiate a defrost cycle and means to reset the defrost cycle upon sensing the defrosting of the refrigeration system. The circuit comprises: first means to sense whether the duration of each defrost cycle exceeds a certain period; and second means, responsive to the first means sensing that the duration of a given cycle exceeded the certain period, for electrically decoupling the reset means from the refrigeration system, for resetting the given defrost cycle and for enabling the occurrence of and controlling the duration of subsequent defrost cycle.
