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

  1. Unplug the refrigerator from the power outlet.
  2. Locate the temperature sensor (thermistor) harness inside the compartment showing the error.
  3. Ensure the connector is fully seated and that wiring is not visibly damaged.

Technician Only Thermistor and wiring diagnosis/repair

  1. Use a multimeter to verify thermistor resistance values and compare with specifications for the model.
  2. Inspect wiring harness continuity between the thermistor and main control board.
  3. Replace the thermistor if readings are out of spec or repair wiring if damaged.
  4. 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)

🛑 When to Call a Pro:
  • 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)
