Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the microwave before any inspection. Mains voltage is dangerous.
- Step 1 – Check outlet and breaker: Test the wall socket with another appliance and check the household circuit breaker or fuse.
- Step 2 – Inspect power cord: Look for visible damage, cuts, or burn marks. If damaged, the cord must be replaced by a qualified technician.
- Step 3 – Check internal fuse (advanced): Remove the outer cabinet and locate the main fuse near the mains input. If blown, investigate the cause (e.g., surge, short) before replacing with the exact same type and rating.
- Step 4 – Inspect mains filter and wiring: Check the mains interference filter and wiring for signs of burning or loose connections.
- Step 5 – Control board diagnosis: If the fuse and wiring are good, the control board's power supply may have failed and the board will need replacement.
Warning: Never bypass the fuse or use an incorrect rating; this is a serious fire hazard.
