If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Critical safety warning: Inverter-based microwaves use high-frequency high voltage. Only qualified technicians should service the inverter or magnetron.
User-level actions:
- Disconnect power for 10 minutes, then reconnect and test briefly. If E07 reappears, discontinue use.
- Ensure ventilation openings are not blocked, as overheating can trigger inverter protection.
Technician-level outline:
- Unplug the unit and follow Balay procedures for safely discharging capacitors.
- Inspect the inverter board for burn marks, cracked solder joints, or damaged components.
- Check wiring between inverter and magnetron for heat damage or loose terminals.
- Substitute a known-good magnetron or inverter (per service manual) to isolate the faulty component.
Due to the complexity and danger of inverter circuits, replacement of the inverter module or magnetron should be done by an authorized Balay service center.
