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.
