How to Fix / Troubleshooting
Safety: Unplug the microwave before any inspection. Do not attempt board-level repairs without training.
- Power reset: Disconnect power for 10–15 minutes, then reconnect. If E-83 returns immediately, the control board is likely faulty.
- Check outlet: Plug another appliance into the same outlet to verify stable power. Avoid using extension cords or power strips.
- Inspect for surge damage (advanced): If you remove the top grille and control panel, look at the main PCB for burnt components or a burnt smell. Do not touch high-voltage areas.
- Replace control board: In most cases, the main PCB must be replaced as a complete assembly. This should be done by a technician to ensure correct wiring and safe operation.
