Ernie for Model Number WRR56X18FW02 This Whirlpool refrigerator will cool to 58 degrees and no lower. Repair technician has replaced all major components. Works good for a couple weeks and the same problem repeats.
Answer Hello Ernie, you did not mention what major components were already replaced so we will go with a general answer. When this occurs the frost pattern on the evap coil needs to be checked, it would indicate whether there is a sealed system problem or a defrost problem. Also if the compressor is regularly cycling off then the control/thermistor l thinks the internal temperature is correct and has cycled the compressor off. If however, the compressor is running nonstop then the control /thermistor sees the internal temperature is not low enough and is trying to cool down further and that would indicate a cooling /defrost problem.
