Mike March 16, 2023 for Model Number FPFU19F8RFB Customer says the freezer is too cold. I went to the home and found the temperature to be -20 F, and my dilemma is I can't find a teardown video because I believe its either a thermistor or the control board must have a stuck relay. How do I determine if the thermistor is bad ? If the thermistor is good..what determines the control board is bad?
1 Answer Mike, To determine if the thermistor is faulty you would need to pull the thermistor and test it for resistance. The resistance should be 5K ohms at room temperature. If there thermistor is good then you would need to replace the control board. The sensor can be accessed by removing the panel in the back of the unit at the bottom. Read More...
