What Does Error E12 Mean?

The Bauknecht refrigerator error E12 signals a malfunction in the defrost sensor, leading to high internal temperatures and potentially causing frost buildup. This issue may also trigger the overheat protection, affecting compressor operation and resulting in ice melting in the ice bin if present. Regular maintenance, particularly cleaning the condenser coils and ensuring proper ventilation, can help mitigate this problem.

Common Symptoms:

  • High internal temperature or temperature warning on display
  • Ice melting in ice bin (if unit has ice maker)
  • Compressor may not start or may overheat

Possible Causes

  • Overheat protection triggered due to poor condenser cooling (medium)
  • Failed condenser fan (medium)

How to Fix Error E12

DIY Fix Basic cooling system checks

  1. Unplug the refrigerator and pull it away from the wall to access rear panels.
  2. Clean dust and debris from condenser coils using a brush or vacuum.
  3. Ensure adequate ventilation around the unit (avoid tight enclosures).
  4. Plug the fridge back in and observe if error recurs.

Technician Only Inspect and service condenser fan or cooling components

  1. Disconnect power and remove rear access panels.
  2. Test condenser fan motor for proper operation; replace if faulty.
  3. Check compressor thermal protector and associated circuitry.
  4. Verify proper airflow and cooling performance.
  5. Reassemble and test operation under normal load conditions.

Parts needed: Condenser fan motor, Condenser coil assembly

🛑 When to Call a Pro:
