Possible Causes
Loose power cord connection at internal terminal block, Failing internal power supply on main PCB, Overheating of power components, Damaged surge components (MOV, fuse resistor)
How to Fix / Troubleshooting
Safety: Unplug the cooker before opening the housing. Capacitors on the power board can retain charge; avoid touching exposed contacts.
- External check: Inspect the power cord for cuts, kinks, or burn marks. Try a different outlet to rule out supply issues.
- Internal cord connection: Remove the base and locate where the power cord enters the unit and connects to the terminal block or directly to the main board. Tighten any loose screws and ensure strain relief is intact.
- Inspect power board: Look for bulging capacitors, burned resistors, or cracked solder joints around the power supply section of the main PCB.
- Replace damaged components: If the board shows visible damage, replace the main control board. Component-level repair should only be attempted by experienced technicians.
- Re-test: After reassembly, run a long program (e.g., slow cook) with water to verify stable operation.
