How to Fix / Troubleshooting
Critical safety warning: Inverter-based microwaves use high-frequency high voltage that is extremely dangerous. Only qualified technicians should service the inverter or magnetron on these models.
User-level actions:
- 1. Power reset: Unplug the microwave for 10 minutes, then reconnect and test. If E14 reappears, discontinue use.
- 2. Check ventilation and load: Ensure vents are clear and you are using appropriate cookware and food loads (never run empty).
Technician-level actions:
- Inspect the inverter module for burn marks or component damage.
- Test the magnetron for shorts and the inverter for correct output using manufacturer procedures.
- Replace the inverter module and/or magnetron as required.
Due to the risks involved, inverter repairs should be left to professional service centers.
