How to Fix / Troubleshooting
Safety first: Unplug the microwave before opening the cabinet. Internal fuses are not user-serviceable in some regions.
- Step 1 – Verify outlet: Confirm the wall socket has power by testing with another appliance.
- Step 2 – Check plug and cord: Inspect for visible damage. Replace if necessary.
- Step 3 – Internal fuse: A technician can remove the cover, test the main fuse, and investigate the cause of any blown fuse before replacing it with the exact AEG-specified type.
- Step 4 – Control board: If fuses and switches are good, the control PCB may have failed and require replacement.
