TEST 77 should test the defrost thermistor properly based on temperature.

Per the tech data sheet--->You can check the voltage to it on the main control board--->FC Defrost Thermistor Output--->P8-1 to P8-2 should read 5 Volts DC when you have it in TEST 77.

I could not locate the service manual for this model.

Also per the tech. data sheet it should read 2700 ohms at 77 degrees F and 7964 ohms at 36 degrees F.
