Possible Causes
Input voltage outside specified range, Faulty power supply section on main PCB, Loose mains cord connection, Damaged MOV or surge protection components
How to Fix / Troubleshooting
Safety first: Disconnect from mains before inspection.
- Check outlet: Verify the wall outlet voltage is within the range specified on the Binatone rating label using a multimeter. Avoid using unstable generators or low‑quality inverters.
- Inspect power cord: Examine the mains cord for cuts, kinks, or burn marks. Ensure the cord grip and internal terminals are tight.
- Try another outlet: Plug the cooker directly into a different, known‑good outlet without an extension cord or power strip.
- Internal inspection (technician): Remove the bottom cover and inspect the power supply section on the main PCB for burnt components, cracked solder joints, or a blown MOV (surge suppressor). Replace damaged components or the entire PCB as needed.
