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.

In a refrigerator having a cabinet defining a first, below freezing compartment and a second, above freezing compartment, a compressor for cooling said first compartment, a wall having an opening between said compartments, a baffle for selectively closing said opening, first and second temperature sensing means for sensing respectively the temperatures in said first and second compartments, first and second temperature setting means for setting the temperatures respectively of said first and second compartments to user selected first and second temperatures: memory means for storing plural open loop compressor control parameters; and microprocessor means programmed to be responsive to said first and second temperature sensing means and to said first and second temperature setting means to control selectively said compressor and said baffle to maintin said first and second compartments at said first and second user selected temperatures; said microprocessor means being further programmed to detect faults in both said first temperature sensing means and said baffle and, in response, to control said compressor using a predetermined one of said plural open loop compressor control parameters stored in said memory means.
