What Does Error C Mean?
The Whirlpool Refrigerator error code C indicates a potential thermistor or temperature sensor failure, which can lead to fluctuating temperatures and insufficient cooling. Users may also hear unusual humming sounds. This error often points to a wiring issue between the thermistor and the main control board or a defective main PCB. Immediate visual checks of the wiring and connections are recommended to diagnose the issue effectively.
Common Symptoms:
- Display shows letter "C" instead of numeric error codes
- Temperature fluctuations or inability to maintain set temperature
- Possible cooling performance issues
Possible Causes
- Faulty thermistor (temperature sensor) (medium)
- Wiring issue between the thermistor and main control board (medium)
- Defective main PCB (control board) (low)
How to Fix Error C
DIY Fix Basic visual and connection checks
- Unplug the refrigerator from the power outlet.
- Locate the temperature sensor (thermistor) harness inside the compartment showing the error.
- Ensure the connector is fully seated and that wiring is not visibly damaged.
Technician Only Thermistor and wiring diagnosis/repair
- Use a multimeter to verify thermistor resistance values and compare with specifications for the model.
- Inspect wiring harness continuity between the thermistor and main control board.
- Replace the thermistor if readings are out of spec or repair wiring if damaged.
- If sensor and wiring are good, test the main control board for faults.
Parts needed: thermistor (temperature sensor), wiring harness, main control board (if needed)
- If the error persists after checking connections and basic user‑level steps
- If wiring appears damaged and beyond simple reconnecting
- If thermistor testing indicates proper operation but the error remains (potential control board issue)
