Multicooker does not power on at all; no lights or display when plugged in.

Safety first: Unplug the cooker before any disassembly. If you are not experienced with electrical repairs, consult a technician.

• Check outlet: Test the wall outlet with another appliance. Avoid using power strips with resettable breakers that may be tripped.
• Inspect power cord: Look for cuts, kinks, or burn marks. If damaged, replace the cord; do not tape or splice.
• Internal fuse (advanced): Remove the bottom cover and locate the small glass or ceramic fuse on the main PCB near the AC input. If blown, replace only with the same type and rating.
• Board inspection: If the fuse is intact, but there is still no power, the main control board's power supply section may have failed and will need replacement.
