The fresh food evaporator keeps frosting up. I have changed the control board and the evaporator thermistor and still keeps frosting up. I have run it through diagnostics and everything seems to be working fine. Any suggestions. I also would like to know what the resistance readings are on those thermistors.
I have replace the main gemini board and the evaporator thermistor.

Hi. I have attached the tech sheet for you. The thermistor values are on page one of the tech sheet. They should have 5.3k ohms @ 50 deg. 8.8k ohms @ 32 deg. , and 25.9k ohms @ 4 deg. Is the frost build up from a defrost issue I do not believe there is a defrost heater on the refrigerator evaporator. The frost build up could also be from a sealed system issue. I had one that was doing the same thing. I think is was the same model or very similar to this one. It had a ball of ice coming through the fresh food evaporator cover. It did not look like normal frost from a typical defrost issue. I looked at the freezer evaporator at that point and found an uneven frost pattern. It was not getting to proper temps in either section. It ended up being a leak in the sealed system. I did not ever find out where is was leaking at, but I did recharge it once and it lasted 3 months or so before the issue came back. A defrost issue would come back in about 5 days. My best guess would be that the refrigerator evaporator is where the leak is at.
