How to Fix Error F8

DIY Fix Basic checks and safety

  1. Ensure unit is powered and unplugged before inspecting
  2. Check that vents and condenser coils are clean and free of dust/debris
  3. Verify the refrigerator is not in an unusually hot environment

Technician Only Inspect/replace condenser temperature sensor and related components

  1. Unplug refrigerator and access rear condenser area
  2. Locate the condenser temperature/NTC sensor and inspect wiring for damage or loose connections
  3. Test the sensor’s resistance against expected values (requires service manual/schematics)
  4. Replace the sensor if faulty
  5. Ensure condenser area airflow is unobstructed

Parts needed: Condenser temperature (NTC) sensor, Possibly wiring harness or clips

🛑 When to Call a Pro:
