Thread: Fridge cycles between 50F & 37F

  1. #1

    Exclamation Fridge cycles between 50F & 37F

    Model Number: PSC25MSWASS
    Brand: GE
    Age:
    1-5 years

    I have a GE Profile Side by Side. Its about 5 years old. The freezer is working fine but the Fridge is acting strange. Here are the symptoms:

    1. Fridge temp will cycle between 37F - 50F. Fridge is set at 37F. I have a digital thermometer in the fridge to monitor the temp.

    a. When Fridge temp drops condensation appears on the left panel but only the bottom half. When the temp is 37F there is no condensation.

    2. While the fridge temp cycles between 37F - 50F, the temp reading on the display panel always reads 45F. It does not change.

    3. Here are the K-ohm readings on J1 wire harness removed from the control board while power off.

    Freezer: 9F & Fridge: 50F
    pin1 - pin5: 46.8 (Thermistor in fridge but where?)
    pin2 - pin5: 9.9 (Thermistor in the fridge left panel)
    pin3 - pin5: 27.0 (Thermistor in the freezer right panel)
    pin4 - pin5: 39.5 (Thermistor on the freezer evaporator)

    Are my location of thermistor correct?

    I think the problem is with the thermistor in the fridge (pin1 - pin5). What are your thoughts? Thank you and have a blessed day!

    Hi Doc Ryan,

    Thank you for the info. My problem is locating the 2nd thermistor in the fridge. The 1st one is on the left panel half way down; where is the other one? Thank you and have a blessed day!

    Your refrigerator has a "custom cool" unit, there may be one or more sensors located inside that unit. Here is a link to another customer that was having a cooling issue with the custom cool unit, some of the information in this thread may be helpful to you.
