Possible Causes

How to Fix / Troubleshooting
Safety: Allow the unit to cool and unplug before servicing.
- Step 1 – Preheat correctly: Ensure you are preheating the convection mode as recommended in the Bomann manual.
- Step 2 – Check fan operation: In convection mode, verify that the rear fan runs strongly. If airflow is weak, the fan motor may be failing.
- Step 3 – Test elements: Measure resistance of grill and convection elements and compare to specifications. Replace any element with significantly higher resistance or open circuit.
- Step 4 – Sensor calibration: A faulty temperature sensor can cause underheating. Test and replace the sensor if readings are out of range.
