What Does Error E05 Mean?

The Thermador refrigerator E05 error code indicates a malfunction in the evaporator temperature sensor, which may prevent proper cooling and cause unusual noises. This issue often arises from wiring problems or a faulty sensor, resulting in inadequate temperature control and potential frost buildup on the evaporator.

Common Symptoms:

  • E05 displayed on the refrigerator’s control panel indicating an error
  • Potential cooling irregularities or frost/ice buildup on evaporator if sensor data is not received

Possible Causes

  • Evaporator temperature sensor fault (medium)
  • Wiring communication issue between evaporator sensor and main control board (medium)

How to Fix Error E05

DIY Fix Basic checks and reset

  1. Check for obvious signs of wiring damage or loose connections at accessible sensor harness points if safely reachable.
  2. Power off the refrigerator at the wall or breaker for 5 minutes and then restore power to see if the error clears (simple reset).

Technician Only Diagnose and repair evaporator sensor circuit

  1. Disconnect power and access the evaporator area and main control board.
  2. Inspect and test the wiring harness for continuity between the evaporator sensor and control board.
  3. Test the evaporator temperature sensor with a multimeter for proper resistance values per Thermador specifications.
  4. Replace the evaporator sensor if defective.
  5. Repair or replace wiring harness sections if damaged or intermittent.
