IS the damper motor getting 120 volts to it?
The damper is bad.
The damper should be opening if it is getting 120 volts to it. The damper was the issue all along not working causing your temp problems.
If you are getting that reading on the temp display have you replaced the display board?
I had one do that and it was just a bad temp board.
So you have replaced both boards then right?
Did you program the board to your unit?
Try to reprogram the board...make sure you save the program the display should flash after so you know it is saved then unplug the unit and plug the unit for 15 seconds and plug it back in. Let me know if the temps are still goofy.
OK the only thing I can think of is you have the wrong thermistor in the unit. What part number thermister did you get for the refrig section?
Yes it should be around 2000 ohms at room temp 77 degrees.
That is way off, this could be the whole issue. It should read 2000 about unless it is really cold or really hot.
They are the same and that is the part CLICK HERE
No the wires do not matter which way on a thermister, but I checked around 9K ohms would be a temp of 16 degrees just FYI
So the freezer is ok correct?
OK if you want remove the freezer thermister and swap them to see, but the range you are getting on the refrig thermister is way out of range. I would get a new thermister.
Just take out the refrigerator thermister and put it in a glass of ice water. It should read around 7500-8000 ohms or just leave it sit in your room and it should be around 2000 ohms. The new one you order should read around 2000 ohms before putting it in.
