ABSTRACT:
In an improved control for a refrigerator, critical components such as fresh food and freezer compartment temperature sensors, temperature set devices and baffle are sampled to conform that each is operational. Upon diagnosis of a critical component failure or of multiple component failures, the control, using stored control parameters, operates the remaining components in a manner that will continue to preserve food.
