Unplug connector from CON7.
3
Measure resistance between Brown and Brown wires (Drawer Model), or Orange to Orange (Swing Model).
4
If 0 ohm (short): Replace the defrost sensor.
5
If open (infinite/OL): Replace the refrigerator control board (Main PCB).
6
If within range, verify against Temperature Table-3: 23F(-5C)=38.5-36.5kΩ, 32F(0C)=30.5-29.5kΩ, 41F(5C)=24.5-23.5kΩ, 50F(10C)=20-19kΩ, 59F(15C)=16-15.5kΩ.
7
If resistance is normal for ambient temperature, check wiring harness for intermittent opens.
