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

Safety first: Unplug the cooker before opening. If the outlet is suspected, test it with another appliance first.

Steps:

• Verify the wall outlet has power and that any power strip or surge protector is switched on.
• Inspect the power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
• Remove the bottom cover to access the power input area. Locate the internal fuse (often in a small holder or soldered on the board near where the cord enters).
• If you are qualified, test the fuse for continuity. Replace only with the same type and rating if blown.
• Check for loose spade connectors or screw terminals on the power input and main board.
• If the fuse is intact and connections are secure but the unit remains dead, the main control board’s power supply section is likely faulty and the board should be replaced.
