Customer Questions and Answers for Refrigerator Defrost Timer by Whirlpool

Gary, Since this refrigerator has a "static" condenser, you'll need to slide it out and check and clean the tubing on the back, and remove any debris in the area. The room temperature has a lot to do with the "run time" as well, if the refrigerator is in the garage, basement, or a non heated area, the exchange of heat is less efficient and the compressor runs longer, as well as "overloading" the compartments. The click noie every so often, could be the overload on the compressor "closing" or opening, due to the compressor overheating, due to lack of air movement low voltage or extended run time.
