What Does Error 4 Mean?

The Beko refrigerator error code 4 indicates a malfunction in the defrost system, often linked to the defrost heater or temperature sensor. This can lead to excessive ice buildup, poor cooling performance, and prolonged defrost cycles. Regularly check for ice accumulation on the evaporator or freezer back wall, as these are key symptoms of the issue.

Common Symptoms:

  • Refrigerator displays code 4 (or E4) on control panel
  • Excessive ice buildup on the evaporator or freezer back wall
  • Poor cooling performance or frosting issues
  • Defrost cycle appears to run too long or repeatedly

Possible Causes

  • Defrost system malfunction (heater or sensor) (medium)
  • Open or loose sensor circuit (low)

How to Fix Error 4

DIY Fix Basic checks and reset

  1. Unplug the refrigerator from the power source for 10–15 minutes to reset the control board.
  2. Check that the refrigerator doors are fully closed and door seals are intact to reduce excess frost buildup.
  3. Observe whether ice buildup is present on the back wall of the freezer compartment.

Technician Only Defrost system diagnostics and repair

  1. With power removed, access the evaporator compartment and inspect the defrost heater for continuity using a multimeter.
  2. Test the defrost temperature sensor for proper resistance changes with temperature.
  3. Verify wiring harnesses and connectors between sensors, heater, and control board are secure and undamaged.
  4. Replace any failed components (defrost heater, sensor) with model‑specific parts.
  5. Reassemble, power up, and monitor for the absence of error code and proper defrost cycle.

Parts needed: Defrost heater assembly, Defrost thermostat/temperature sensor, Wiring harness/connectors

🛑 When to Call a Pro:
  • If the error persists after basic reset and observable ice buildup remains, contact an authorized technician.
  • If you are not comfortable using a multimeter or opening refrigerator panels, schedule professional service.
