Easy installation and good service
Part came in good time. Always happy with the service from Partsselect.ca. Unfortunately the part did not solve my issue of fridge too cold (and water line freezing).

Refrigerator would ice up around the condenser and through out the air vents. Stopping all air flow in the refrigerator. If you defrosted the refrigerator it would work for about 24 hours then ice up again.
Unplugged and empty refrigerator, completely defrosted refrigerator using a hair dryer to speed up the defrosting, put a lot of towels on the floor to soak up the water when the ice melts. Removed all refrigerator racks and drawers, then remove the white plastic and styrofoam condenser cover. You will then see the thermistor, cut the two small wires connecting the thermistor to the harness leave yourself as mush wire as possible. Splice in the new thermistor and put the refrigerator back together.

Lower Freezer worked fine, but upper refrigerator would not cool.
I first replaced the lower (freezer) evaporator thermistor based on recommendation from other feedback, however that did nothing to resolve the problem. I subsequently discovered a diagnostic document hidden under the upper right door hinge, which helped me narrow the problem down to the upper (refrigerator) evaporator fan motor. After replacing the fan motor, my refrigerator is up and running again. The only challenge was accessing and removing the access panel(s) and air column. Once those were removed, replacing the fan motor was simple.

My freezer side works fine but the refrigerator side is freezing food. Temperature is already set at 45 degrees but still freezing food. Thank you!
For model number KSF26C4XYY03
Hi Dave, Thank you for the question. I suggest testing the Bi-Metal Defrost Thermostat, PartSelect Number PS11750673.The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Why are there 2 different thermastors listed for my model #? How do i know which one to order?
For model number WRF560SMYW04
Hello Sharon, Thank you for your inquiry. Part# WPW10383615 is the temperature sensor that goes on the freezer evaporator, part# W10316760 is the thermistor kit for the freezer and refrigerator which checks the temperature of the freezer and fridge and sends it to the control board.Hope this helps!

I am trying to find the bi metal defrost thermostat for my refrigerator. Is this it, just called a different name? My coils in the freezer keep freezing solid and the temperature in the fridge will slowly climb until i turn the whole unit off and let it thaw.
For model number kbfs20ecms00
Hello J, Thank you for your inquiry. A thermistor is a temperature sensor-which detects the temperature in the fridge and sends it to the control board. The defrost thermostat for your model is part# W10911102 which also comes with the wiring harness-we have it labeled as just a wiring harness but the defrost thermostat comes with it. Hope this helps!

Whirlpool freezer fan was making noise. Took everything apart and freezer coils were frozen solid. Fan seem good .The evaporator heater wire measures about 32 ohms. Could the evaporator temp. Sensor be the problem? The clip is very loose on the cooling coil, if that makes any difference

Ice is building up in the refrigerator side. The freezer works fine. I already replaced the refrigerator defrost thermostat. Any more parts to replace to fix this issue?
For model number KSC23C8EYY03
Hello Art, thank you for your question. We would recommend replacing the PartSelect Number PS2580944 Thermistor. This is the thermostat for the unit and takes the internal temperature and relays it to the unit. It sounds like the thermistor isn't working properly. I hope this helps!

My freezer does not defrost. Would the thermistor be the problem?
For model number WRF736SDAM13
Hi Mike,
Thank you for your question. If your freezer is not defrosting, there are some parts that you will need to check to see which one is causing the issue. You will need to check the defrost heater assembly and the main control board. I hope this helps. Thank you and have a great day!

Food in freezer gets significant frost / ice buildup. Even food wrapped in envelopes in boxes, i.E. Eggo waffles in their purchase containers. Have had technician out. Checked gaskets which all appeared to be in good shape. He said that there was an evaporator upgrade kit but since fridge is out of warranty the cost was prohibitive but might be an answer. Had an older Whirlpool fridge side by side which we had for 15 years and never had such a problem. Also, in the parts illustration / listing, is there any where that mentions what specific part / parts are supposed to do??? i await your response, thanks
For model number WRF989SDAE00
Hello Ben, Thank you for your inquiry. We would recommend checking the following parts to fix your issue: evaporator and evaporator motor, icebox/evaporator fan motor, damper control, and defrost heater. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!

I asked earlier if it could be the thermistor causing fluctuating fridge temps. The answer i received was it could also be that or evaporator or drain. Can you please tell me where the evaporator and drain are located? And we just ordered the thermistor. We were told it is in the freezer back panel. Want to make sure before we remove ice maker and shelves. This is a KitchenAid french door bottom freezer. Also the temp started fluctuating after i had doors open for a while, while i was cleaning and taking out shelves to clean ect. Thanks
For model number KBFS22EWMS9
Hello Roger, thank you for writing. The Evaporator, part number PS11752680, is located in the upper back part of the refrigerator behind the rear panel. We have a video showing the installation of the P-Trap Drain Tube, part number PS8691807. Here is the link: https://www.youtube.com/watch?v=abKsJn_7I-A&. I hope this helps, and good luck with your repair!

Is part number w10316760 compatible with model wrb 329dmbm
For model number WRB329DMBM
Hello Jim, Thank you for contacting us. No, that does not show compatibility. I have researched the model you have provided and have found the part you’re looking for is Thermistor - PS2003772.
Freezer works fine, fridge will not cool below 45 degrees F. Ran diagnostics test. Refrigerator evaporator thermistor alternately reads both "13" and "2-". All other thermistors read ok. Does this mean the refrigerator evaporator thermistor has failed and, if so, what is the correct ct part number?
For model number kbfn402ess01
Hello Hamilton, thank you for the great question. Yes our research shows that the evaporator thermistor part number PS16875905 is the part that you need. We hope this helps.
