How to Fix / Troubleshooting
Safety: Unplug the microwave before opening any panels. Internal fuses are not user-serviceable in many regions; check local regulations.
User-level checks:
- Outlet test: Plug another appliance into the same outlet to confirm power is present.
- Circuit breaker: Check the home breaker or fuse panel for a tripped breaker.
Technician-level checks:
- Remove the outer cover to access the line fuse and line filter board.
- Test the fuse for continuity and replace only with the exact type and rating specified by Electrolux.
- If the new fuse blows immediately, test the door switches, line filter, and high-voltage components for shorts.
- Inspect the power cord and connections for damage.
