Jim for Model Number Kenmore Elite 79574015411 refrigerator Refrigerator compartment does not cool down completely. Refrigerator evaporator coils are cold. Fan does not come on. Door alarm beeps. I understand that if the door is open or the temperature is warm it will alarm. How can I tell which part has failed, door sensor, control board or could it be the temperature sensor.
Answer Jim, You can test the door switches to make sure that they are good by testing for continuity. If the door switches are good but the fan is not coming on check to make sure that the fan is getting power to it and if it is then the fan is the issue. The sensors can be tested for resistance at the control board and the resistance will depend on the temperature inside the unit. At 70 degrees it should have a resistance of 5K ohms. If all this checks ok then the control board will be the most likely cause. Read More... Answered by AppliancePartsPros.com | Tuesday, July 6, 2021
