Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave-oven combo before any internal inspection. Heating elements and fans can be live and very hot.
User-level checks:
- 1. Confirm mode: Ensure you are selecting a convection or grill mode correctly per the manual.
- 2. Listen for fan: When starting convection, listen for the internal fan. If silent and no heat, E16 likely indicates a convection circuit fault.
Advanced steps:
- 3. Access rear panel: Remove the outer cover to access the convection heater and fan assembly.
- 4. Test heater element: Disconnect and measure resistance. An open element must be replaced.
- 5. Test convection fan motor: Check for free rotation and continuity. Replace if seized or open.
- 6. Check thermal cutouts: Test any thermal fuses or thermostats in series with the heater for continuity.
If all components test good, the control board relay or drive circuit may be faulty and require replacement.
