This small but important part helps your fridge defrost safely. It keeps an eye on the temperature of the coils and shuts off the heater when things get warm enough. That way, your fridge doesn’t overheat and keeps working properly. If you’re seeing frost build-up or your fridge isn’t cooling right, this thermostat might need replacing. It’s usually clipped onto the coils and connected to the defrost system.

Easy to replace
Excellent service and fast shipping. This was an easy part to replace thanks to the correct wiring connections. I couldn’t find a lot of detail regarding which line the defrost thermostat should be on and questioned if it was on the right line. After sharing photos with an experienced repair person, we determined it was previously installed on the wrong line. This should fix our issue with random high temperatures in the refrigerator and freezer. Thank you Part Select.

Fixed the problem perfectly
Received this part because the freezer kept getting way to warm, took a long while to defrost and change out but ever since it has worked perfectly. Easy to follow the video instructions and get this done. Appreciate the website helping me find out what was wrong and solve it instead of paying someone to do it!

Freezer compartment is getting ice build up back corner below ice maker & on backwall
For model number fgun2642lf2
Hello Mike, thank you for your question. The most likely issue is with the thermostat or the heater itself. More often the thermostat needs to be replaced. Test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter. Also check the motor to be sure its turning and blowing cold air into the fridge from the freezer. I hope this helps!

My refrigerator has been running at a high temperature. With the freezer running normal, by replacing the defrost thermostat will I fix the issue. Large amounts of frost has accumulated in the evaporator coils and I noticed that the attached defrost thermostat has the cap removed. Your thoughts.
For model number FGHN2866PF1
Hello Carl, Thank you for the question. We suggest testing the Defrost Thermostat. 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. We hope this helps!

Will a faulty defrost thermostat cause the freezer temperature to get warmer?
For model number FPHF2399MF7
Hello Ryan, Thank you for the question. Yes, a defective Thermostat can cause the temperature to fluctuate. The Thermostat can be tested. 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.

Been Manually defrosting my freezer every few weeks when the temp starts to rise. I replaced the thermostat as recommended in the others. This time I checked it and it read closed when I pulled it (frozen). It measured open after it warmed up, so I put it back in. What do I check next?
For model number FGHB2844LF7
Hello Thomas, thank you for contacting us. We have researched the model and would suggest checking the defrost heater, part number PS2369212, for continuity using a multimeter. We hope this helps!

how do I turn off ice maker, If I pull out ice tray will it stop it
For model number LGUB2642LE3
Hi Walter, thank you for reaching out. Based on our research, you can turn the ice maker on or off by lifting/lowering the ice maker's wire signal arm. To gain access to the ice maker, pull the freezer drawer out. Lift the wire signal arm to turn the ice maker off. We hope this information helps!
