What Does Error 3 Mean?

The KitchenAid refrigerator error code 3 indicates a potential malfunction in the evaporator fan or issues with the temperature sensor (thermistor). This may lead to the refrigerator running warmer than usual and could produce unusual sounds. If this error occurs, it is essential to check the temperature readings and ensure the unit is maintaining the set temperatures effectively.

Common Symptoms:

  • Refrigerator display shows code 03
  • Possible unusual temperature readings or failure to maintain set temperatures
  • May occur after power interruption or during normal operation

Possible Causes

  • Faulty temperature sensor (thermistor) or sensor communication error (low)

How to Fix Error 3

DIY Fix Basic checks and reset

  1. Unplug the refrigerator from power for 5 minutes to perform a soft reset (ensure food safety during power-off).
  2. Check if the error disappears after power is restored.
  3. Monitor refrigerator temperatures to see if cooling performance is normal.

Technician Only Inspect temperature sensor and wiring

  1. Disconnect power and access the refrigerator’s thermistor (temperature sensor).
  2. Visually inspect sensor and wiring harness for damage, corrosion, or loose connections.
  3. Use a multimeter to test sensor resistance against manufacturer specifications.
  4. Repair or replace a faulty thermistor or wiring as needed and verify control board communication.
  5. Reassemble and test operation to confirm error resolution.

Parts needed: Thermistor (temperature sensor), Wiring harness/connectors

🛑 When to Call a Pro:
  • If error 03 persists after reset and basic checks
  • If sensor testing indicates fault but replacement is beyond user capability
  • If temperatures remain outside safe range indicating possible broader system issues
