Scott for Model Number PSF26PGTBBB My GE dual evap fridge and freezer were having huge temp swings. Up to 20 in the freezer and 50 in the fridge. The main board, temperature sensors (1 in fridge/2 in freezer) and defrost thermostat have been replaced. The defrost heater in the freezer has been on a couple times that I have noticed. The temp in the freezer has been more consistent but still 5+ degree swings. The fridge averages 6-9 degrees above the 37 degree default. Since replacing the parts above, the one thing I have noticed is that the compressor is sometimes not running even though temps are high. But, if I open the freezer door and push the door switch (or close the door), the compressor will immediately kick on and evap fan starts blowing - 9 out of 10 times at least. I think the compressor shutting off may be the key to the problem of high / unstable temps. What should I try next?
Answer Scott, You will want to test the sensors in the refrigerator sections. The sensors should read approximately 14.4K ohms at 37 degrees and 5K ohms at room temp. It is more likely that the sensor having a loose connection. The if there was an issue with the compressor then the freezer section would not work properly. Read More...
