Possible Causes
How to Fix / Troubleshooting
Critical safety warning: Inverter-based high-voltage systems operate at lethal voltages and frequencies. Do not attempt to service the inverter or magnetron yourself.
User-level checks:
- 1. Power reset: Disconnect power for 10 minutes, then reconnect and test a short heating cycle with a cup of water.
- 2. Ventilation: Ensure vents are clear to avoid overheating that can stress the inverter.
If E11 reappears, the inverter or magnetron assembly requires professional diagnosis and likely replacement.
