My issue is the fresh food side won’t cool properly. History of the unit and repairs. Since summer time 2012, the freezer would bounce between 0-10 on a normal basis, and the fridge was usually 42-49, with the temp controls set at 0 and 37. Finally got tired of food spoiling, and decided to start tearing into it. Through research, found a bad defrost heater element, one end was burnt. Replaced, and started keeping a very close eye on temps now. Freezer improved, but fresh food side did not. Took the next logical plunge, and replaced the system board. A week or so later, fridge went bezerk, started running all the time, temps displayed were 20 freezer and 80 fresh food. At the same time, everything in the fridge was freezing, which is what causes me now to be baffled, as I know it has the ability to keep things cold to the point of freezing them. Found it to be a bad fresh food thermistor, located in the side wall of the fresh food compartment. Replaced it and when things got back to my normal, -3 to 10 freezer and 42-49 fresh food, I also replaced the same thermistor in the freezer section in the side panel. Things have not improved. I had stocked the fridge a week ago and the freezer, left the door closed for 48 hours and then checked temps, -3 freezer, and 45 fresh food. My only other thoughts are to replace the two remaining thermistors, and the defrost thermostat. I know the doors seal well, and I have even checked to make sure that the lights aren’t staying on causing it to heat up, and again, the fact I found from the bad thermistors, it has the ability to freeze food in the fresh food section, so something is telling it to not cool enough....[COLOR="Red"]Please read completly...[/COLOR]....someone suggested the temperature control board, and someone has suggested the evap fan....the reason why i question both of these, is, when the fresh food thermistor was repalced, all the fresh food side was frozed, and the fridge was running non stop, and was told at that time to replace the temp control board, because the temp inside the unit was not reflected on the display correctly, as the food was frozen but the display said it was 80 deg. Yes i replaced the thermistor, and the temp control panel now reads the correct temp for what it is inside the fridge

No...it's not cooling...temps are all over the place...freezer is between -6 and 10...fridge is 46-49...and the fresh food can runs constantly.....

The part that is confusing to me is, two weeks ago before the two thermistors were replaced, it was freezing all the fresh food side items...yet was reading that is was 80...so I guess my though is, it has the ability to cool properly and then some, but it's not able to regulate the cooling.

So before I replace the temperature control board that has been suggested, my thought is to replace the other two thermistors on the freezer and fresh food coils and the defrost thermostat. What do you think.

I'll give that a try...it seems to me like its for lack of a better term has it's wires crossed somewhere...since it was freezing things, and now with the new thermistors the fridge temps match the displayed temps, if I didn't cover that earlier, that when the thermistor were replaced, the fridge was. Freezing food but the display read 80...and that problem was fixed by the thermistors

I was informed before, if you left the temp control board unplugged, the fridg. should default to the factory settings of fridg 41, freezer 5 degrees

Check the compressor in the back, might be overheating and shutting down on it's thermal overload.
