Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave. Internal fuses are not user-serviceable in some regions; check local regulations.
Step-by-step checks:
- 1. Verify wall outlet: Test the outlet with another appliance to ensure stable power. Avoid using long or undersized extension cords.
- 2. Power reset: Unplug the microwave for 10 minutes, then reconnect directly to a wall outlet.
- 3. Check internal fuse (advanced): Remove the cabinet and locate the mains fuse near the power cord entry. Inspect for a blown fuse (darkened glass or broken filament). Replace only with the exact same rating and type if allowed in your region.
- 4. Inspect the control board: Look for burned components or swollen capacitors in the low-voltage section.
Warning: If the new fuse blows immediately or E07 persists, there is likely a deeper fault in the power supply or high-voltage section. Do not keep replacing fuses; contact a professional technician.
