Possible Causes
Overheated magnetron, Failed magnetron, Faulty thermal cutout on magnetron, Wiring issue between magnetron and inverter
How to Fix / Troubleshooting
Critical safety warning: Do not attempt to access the magnetron or high-voltage wiring yourself.
User-level steps:
- Allow cooling: Unplug the Café microwave and let it cool for at least 30 minutes.
- Check ventilation: Ensure all vents are clear and cabinet clearances meet specifications.
- Test with water: Restore power and run a 1-minute cook with a cup of water. If E50 returns or there is no heating, internal components are likely faulty.
- Service required: A technician should test the magnetron, thermal cutouts, and inverter/transformer, and replace the failed part.
