Follow-up to this:
Freezer cold - refrig not. Not defrost problem. New motherboard, new thermistors, thermostat/heater checks out. Damper isn't opening. When I open it manually, it cools - stays open for a while, then closes and does not appear to open again on its own. With door closed, refrig stays at 52-54 degrees. New thermistor - getting 9.975K ohms @ 54 degrees. At 32 degrees ice water), 15.4K ohms. Also, the readout atop the door doesn't come on when the door is opened. Not even when the door switch is flipped. Does come on when you touch any of the "colder/warmer" controls. Any relation between the two issues. Also, when I opened the damper door manually, started to get clicking/chirping from what appears to be fan compressor motor. I realize it is probably two entirely separate issues but is there any possible relation there? As of now, clicking/chirping is pretty constant without regard to damper door.

Answer Jim, Are you checking the resistances at the main control board ( white/ yellow, and blue/white wires) The refrigerator thermistor sends the signal to the main board, the main board sends the signal to the damper motor to make it run, until the switches open or close to stop the motor. You'll want to check the connections and wires to the damper assembly, and replace the damper WR09X10050, if all appears OK.
Checking he resistance at the J1 plug - 5 and 2,3,4. I purchased new damper and installed. Still have the problem.
Interesting issue: The gasket for the new damper didn't hold (yes I removed the backing) and the damper fell out. With no damper, cold air flows in (obviously) and the temp on the refrig side goes as low as upper twenties but from time to time gets as high as the low fifties. ?? When heater comes on??
And - freezer is generally cold but water is gathering at bottom and freezing. Same thing inside ice bin. ??
And still would like to know why readout inside top of door frame doesn't come on without pressing colder/warmer. Is this a clue to...anything?
ANSWER Hello Jim. It sounds like 2 issues here. It sounds like the fan motor needs to be replaced as well as the damper assembly in the unit. The 2 parts do not work together to affect the unit in this manner. You will need to replace both parts on the unit.
