What Does Error E5 Mean?

The E5 error code on your Blomberg oven indicates a cooling fan circuit fault. This may result in the cooling fan running continuously, intermittently, or not at all, and could lead to the oven shutting down unexpectedly or failing to reach the desired temperature. Common causes include a failing cooling fan motor, obstructed airflow, or faulty control on the PCB. Immediate attention is recommended to avoid further issues.

Common Symptoms:

  • Oven display shows E5 or E05
  • Cooling fan runs continuously, intermittently, or not at all
  • Oven may shut down unexpectedly or fail to reach/set temperature

Possible Causes

  • Cooling fan motor failure (medium)
  • Obstructed or blocked fan / airflow path (medium)
  • Faulty fan control on the PCB (fan triac/relay) or wiring issue (medium)

How to Fix Error E5

DIY Fix Initial inspection and reset

  1. Turn off and unplug the oven or switch off its circuit breaker.
  2. Wait 5–10 minutes and restore power to see if the code clears or reoccurs.
  3. Observe if the cooling fan spins when the oven is turned on (careful, do not touch moving parts).

Technician Only Fan assembly and circuit inspection

  1. Disconnect power at the mains and access the oven’s cooling fan area.
  2. Visually inspect the fan for obstructions, damaged blades, or seized bearings.
  3. Test fan motor resistance and verify it spins freely by hand.
  4. Inspect wiring harness continuity between fan and control board.
  5. Test/replace fan drive circuitry on the control PCB if motor and wiring are good.

Parts needed: Cooling fan motor, Fan assembly hardware, Control board (fan triac/relay area)
