How to Fix / Troubleshooting
Safety: If you smell burning plastic or insulation, switch off the oven and breaker immediately. Do not continue using until inspected.
- Visual inspection: After cooling and disconnecting power, remove rear and top panels to look for discolored or melted wiring, connectors, or components.
- Check fan motors: Spin the cooling and convection fans; if stiff or noisy, replace the motor before it overheats further.
- Inspect control board: Look for burnt spots or components on the EOC or power board. Replace any damaged board.
- Clean cavity: Remove any burnt food or grease from the oven interior that could cause persistent burning smells.
