How to Fix

1
Check for loose connection in CON7 on Main PCB.
2
Unplug connector from CON7.
3
Measure resistance between White and White wires.
4
If reading is 0 ohm (short): Replace the refrigerator sensor.
5
If reading is open (infinite/OL): Replace the refrigerator control board (Main PCB).
6
If reading is within normal range, verify against Temperature Table-2: 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 matches table for ambient temperature, sensor is good — inspect wiring harness.
