What Does Error E04 Mean?

The Electrolux refrigerator error E04 indicates a fault in the room temperature sensor, leading to fluctuating or incorrect temperature readings and compromised cooling performance. This issue often arises from a damaged or open thermistor connected to the control board, affecting the refrigerator's ability to maintain a stable environment for food storage.

Common Symptoms:

  • Temperature display may be incorrect, unusually high, or fluctuate
  • Refrigerator may stop cooling properly or run unusually
  • Error code reappears after power cycling

Possible Causes

  • Faulty refrigerator room temperature sensor (thermistor) on the power/control board (medium)

How to Fix Error E04

DIY Fix Basic checks and resets

  1. Unplug the refrigerator from power for 2–3 minutes, then plug it back in to clear the error and see if it returns.
  2. Check that the refrigerator doors are fully closed and seals intact (temperature sensors can trigger errors if doors are left open repeatedly).
  3. Ensure there is no excessive heat load in the refrigerator (e.g., large recent food load or warm room environment).

Technician Only Inspect/replace the room temperature sensor and related wiring

  1. Disconnect power and remove access panels to access the control/power board.
  2. Visually inspect the room temperature sensor and its connector/wiring for damage, looseness, or corrosion.
  3. Using a multimeter, test the thermistor resistance at known temperatures to confirm open/short conditions.
  4. Replace the sensor or control board assembly if the sensor is out of specification or damaged.

Parts needed: Room temperature sensor (thermistor), Control/power board (if sensor is integrated)

🛑 When to Call a Pro:
  • If error persists after power cycling and basic checks
  • If you are uncomfortable testing or replacing electronic control components
  • If other symptoms (e.g., no cooling, odd noises, refrigerant smells) accompany the error
