Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the microwave. Internal fuses are not to be bypassed; they are safety devices.
Step-by-step checks:
- 1. Check outlet: Verify the wall outlet has power by plugging in another appliance.
- 2. Inspect power cord: Look for cuts, burns, or kinks in the Paderno microwave power cord.
- 3. Access internal fuse: Remove the outer cabinet and locate the main line fuse near the power cord entry. Do not touch high-voltage components.
- 4. Test fuse: Use a multimeter to check continuity. If open, investigate for shorts before replacing.
- 5. Replace with identical rating: If no obvious short is found, replace the fuse with the exact same type and rating specified by Paderno.
- 6. If fuse blows again: There is likely a deeper fault in the power supply or control board. Discontinue use and contact a technician.
