Dan for Model Number PSS27SGRESS I had a cooling issue (the inside light went out and the refriderator temperature wnet up to 50+ while the freezer was OK) and water/ice delivery(water inconsistant and no ice what so ever) issue with my GE refriderator model PSS27SGRESS. Based on forums and other data, I replaced the motherboard and the water valve. For about a day or two the refridgerator worked great with no issues.Today the refiderator is having the same cooling issues again (except the refriderator light is still on now), I have checked the door switches and they are OK and there is no excess frost built up in the freezer. The little bit of research I've done says to replace the temperature control panel, but I don't want to just throw parts at it since that is over $100 on your site. I'd like to be fairly sure that is what needs to be replaced.
Answer Dan, You should check the thermistors in the refrigerator compartment to make sure that they are good. The resistance values are as follows: at 77 degrees 10K ohms, 37 degrees 14.4K ohms, 0 degrees would be 42.2K ohms. If not within range then you would want to replace the thermistor. Also check to make sure that the damper door at the upper left of the refrigerator compartment is not stuck closed which would also cause the issue. If all this checks ok then the display board would be the issue. You can check the thermistors from the main control board. Read More... Answered by AppliancePartsPros.com | Monday, January 20, 2014
