Mavis for Model Number PSHW6YGXCDSS 12-year-old GE Profile side-by-side working great on the freezer side, fridge side fluctuating between 39-50 degrees even though it is set to 35. Usually, about 48, even if it's during the night when people are asleep. LCD display temp on the panel accurately shows 0 for the freezer but display temp for the fridge shows 35 even though the fridge is 10+ degrees hotter. Repairman determined the fan is running and the compressor is running. He then removed the temp sensor from the inside of the fridge and when he realized he didn't have that part on his truck he put the old sensor back in. Oddly enough it started working again and has worked perfectly for 5 days. The LCD temp agrees with (is close to) the temp monitoring device I still have in the fridge and they both show that it stays within the normal range. The food is colder now in the fridge. Should we be replacing the temp sensor anyway (since the repairman didn't) or wait for this one to have a problem? One other thing noted by the repairman was that the drain pan under the fridge was bone dry and has been that way for some time so GE said to replace the compressor, but honestly, everything looks perfectly normal now that temp sensor was reconnected.
Answer Mavis, as the temperature sensor is a resistance based part, it is unlikely that it is bad as it would not have a way to reset itself into having the proper resistance. The thermistor can be tested for resistance at the main control and compared to a resistance chart for correct readings. This will allow the identification of whether the issue is with the sensor or the main control. However, if the compressor is running for a very long time to keep the unit at the proper temperatures, then it is likely that there is a compressor issue. Read More...
