How to Fix / Troubleshooting
Safety: Repeated shutdowns can indicate an internal fault; avoid repeated restarts.
User checks:
- Plug the microwave directly into a dedicated outlet (no extension cords or power strips).
- Verify the circuit is not overloaded with other high-wattage appliances.
- Allow the unit to cool for 30 minutes and try a short test.
If problem persists:
- An internal component (e.g., magnetron, transformer, thermal fuse) may be overheating or drawing too much current. Professional diagnosis is recommended.
