Possible Causes
Open grill heating element,Failed convection fan or motor,Defective grill thermostat or thermal cut-out,Faulty relay on control board for grill circuit
How to Fix / Troubleshooting
Safety: Unplug the microwave and allow all internal parts to cool before inspection. Heating elements can remain hot.
User checks:
- 1. Confirm mode: Ensure you are selecting a grill or convection program correctly according to the Blomberg manual.
- 2. Listen for fan: In convection mode, you should hear the convection fan. If silent and E14 appears, the fan or its circuit may be faulty.
Advanced steps:
- 3. Inspect grill element: Remove the top or rear cover (depending on model) to access the grill element. Look for breaks, burn spots, or disconnected terminals.
- 4. Test element and thermostat: Use a multimeter to check continuity of the grill element and any inline thermostats or thermal cut-outs. Replace any open components.
- 5. Check convection fan motor: Verify that the fan blades spin freely and that the motor windings have continuity.
