How to Fix Refrigerator Error

Unplug refrigerator.
Locate freezer thermistor: behind rear interior panel near evaporator coils (small white sensor clipped to evaporator tubing).
Disconnect thermistor harness.
Measure resistance at room temperature (70°F): should read 8,000-10,000Ω. At 32°F: ~7,964Ω. At 0°F: ~23,345Ω.
If reading infinite (open) or 0Ω (short), replace thermistor WPW
If resistance within spec, check wiring harness continuity back to main board J3 connector – look for pinched wires near hinge areas.
If wiring good but code persists, test defrost thermostat WPW10316428 (clipped to evaporator) – should read closed below 40°F.
Last resort: main control board W10868991 has failed ADC circuit – replace board and reprogram.
