    Default Freezer TOO COLD!! 20 Below Zero

    Model Number: KSRA25ILSS02
    Brand: KitchenAid
    Age: 6-10 years

    I'm having a recurring problem that I first found when my defrost drain froze up. My freezer, which is set to 5 degrees, is running from -16 to -24 degrees F. Ice cream is ROCK hard and you are greeted by a cascading cloud of fog when you open the door.

    I've done a total thaw down and cleaned the drain out. I took the cold air baffle out and it works fine, opening and closing. The fridge section is perfect temp, but the freezer is too cold. It seems like the freezer thermistor, or the control panel, has gone south and it just keeps running.

    I tried to find a troubleshooting guide on line but can't find one. Can someone offer up a suggestion or point me to some diagnostics?

    Thanks,

    -RFL

    Hi RFL,

    Yes, The temperature issue would either be caused by a bad thermistor or control board, thats the only parts that controls the temperature.

    The thermistor is #13 here: Refrigerator Liner parts for Whirlpool KSRA25ILSS03 - AppliancePartsPros.com

    You have to remove the #17 channel, and #16 cover to access it from the refrigerator section. To test it you ohm it with an multimeter, you put the sensor in cup of ice water for 5 minutes and it should read about 8.7 K ohms.

    Here's the thermistor for your model you can order here:

    Here's the control board for your model you can order here:

    Jake,

    Thank you for the reply. The thermistor check is most helpful.

    OK, I pulled out both thermistors and checked each in an ice bath. I goofed and didn't keep them separated so I could know which came from where. One was 7.8 kohm and the other was 8.51 kohm. As a test I installed the higher reading unit into the freezer so the controller will think the freezer is colder than it would if the 7.8 kohm reading thermistor were installed.

    When I checked this morning, the freezer was a +2 F (set at 5F) which is a whole lot better than the -18 or so we see so often.

    Maybe it was just unplugging and plugging in the components that cleaned the contacts or maybe nothing happened at all happened. All I know is the freezer was at an acceptable temp this AM. Time will tell.

    Hopefully this is the end of the problem.
