I have a GE Profile Artica (Model # PSS25SGNBS) which has a digital thermostat inside the unit. About 2 months ago, I noticed that the food in the refridgerator was freezing, even though I kept the refrigerator portion set at the recommended temperature (37 degrees). The temperature fluctuates between 26-31 degrees; which is freezing the food. I even tried adjusting the temperature setting to 42 degrees with no change. Also the freezer fluctuates from -1 to -5 even when we keep setting it to zero with the digital control. The ice maker freezes up and stops making ice. I have also had water leakage from the freezer side of the water line causing damaged or to our nice wood floor. We had a appliance repairman in and he replaced the thermostat sensor but we still have the problem of too cold and still leaking. Any ideas what is causing this and how to fix it?
