Temperature Sensor

Hello Patrick, Thank you for the question. I recommend testing the sensor. 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!

Hello Cole, thank you for inquiring. Yes, the Temperature Senor is a likely cause. This part number PS4138666 is the compatible replacement for your model refrigerator. You may also want to consider the Damper Motor, part number PS4138340. Good luck with your repair!

Hi Robert, thank you for your question. When you are having temperature problems in your fridge, there are a few parts that could cause the issue. You can use a multi meter to test most of the parts. Make sure you cut power to your appliance before doing any repairs or tests. First you should test your defrost thermostat. Place the thermostat in ice cold water for 2-3 minutes after removing it from your appliance. It should be reading 0 ohms to be working correctly. Another part to check would be your defrost heater. Remove it from the appliance. It should be reading anywhere between 0 - 50 ohms to be working. You could check your temperature sensor. To find the correct reading for this part you will have to refer to your tech sheet that comes with your appliance. You can usually find this tech sheet behind the bottom grille of your fridge on either the right or left side. These are the most common parts that cause this issue in your appliance. So it is suggested you check them first. I hope that helps. Good luck with your repair.

Hi Daniel, Thank you for your question. No, I have listed the correct part down below for you. Good luck with your repair.

Hello Chuck, thank you for your question. We would recommend testing or replacing the sensors in the fridge Part Number: PS4138686 and Part Number: PS4138666 which are in the back of the fridge behind the back wall. I hope this helps!

Hello Dennis, Thank you for the question. We suggest testing the sensor. At 70 degrees the resistance should be 9.3K ohms, 90 degrees would be 7.7K ohms. at 100 degrees would be 6.2K ohms, and 120 degrees would be 4.3K ohms. If the thermistor reads outside of range then it needs replaced. We hope this helps.

Hi Ed, thank you for reaching out. According to our research, you may need to check the following parts to fix the issue: temperature sensor, part number PS4138666, bi-metal defrost thermostat, part number PS4140510, PCB main assembly, part number PS12083032, defrost heater, part number PS4140530, and the refrigerator evaporator fan motor, part number PS9603956. We hope this sorts out your problem!

Hello Charles, Thank you for your inquiry. Researching the model number that you have provided, we show that this sensor is the same part number for both the refrigerator and freezer sections. We hope this helps you.

Hello Ron, thank you for your question. The Temperature Sensor in your refrigerator senses the temperature and sends the information to the Electronic Control Board. If the temperature in your refrigerator is not accurate, it could be due to the Temperature Sensor. I hope this helps!

Hi Dennis. Check the evaporator fan, compressor and if the coils have frost buildup. If so you may need to manually defrost your freezer. Thank you for your question and good luck with your repair.
