How to Fix / Troubleshooting
Safety first: Unplug the unit before opening any covers.
- Check outlet: Test the wall outlet with another appliance or a meter to confirm proper voltage.
- Inspect power cord: Look for cuts, burns, or loose prongs. Replace the cord set if damaged.
- Internal fuse: Access the main PCB and check the onboard fuse. Replace only with the same type and rating if blown, and investigate for underlying shorts.
- PCB replacement: If the power supply section is visibly damaged (burn marks, bulged capacitors), replace the main control PCB. This should be done by a qualified technician.
