We have a whirlpool side by side refrigerator with digital temperature controls. Came with the ice and water dispenser too. Freezer temperature seems to work fine. But the fridge temp won’t stay true to its temperature. We set the recommended temperature to 37 but it froze stuff. We set it up to about 39 or 40 but it would come out lukewarm to maybe room temperature. When we put it back to 37, it froze stuff again.
@gencyannie could be a thermostat issue. Temperature Control Thermostat If the refrigerator does not get cold enough the temperature control thermostat might be defective. The thermostat allows power to flow through to the compressor, evaporator fan and condenser fan. If the cooling system fans and compressor are running, but the refrigerator or freezer is not cooling correctly check for an airflow or defrost system problem. If you can let us know what model this is exactly we may find more information about this. There are issues with the WRT series about not having placed the thermostatic bulb in the right location. Hence the importance to know what model you have.
