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

Safety first: Ensure the outlet is not live while you are working on the plug or cord. Unplug the cooker before opening any panels.

• Check outlet and cord: Test the wall outlet with another appliance. Inspect the Nesco power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
• Try a different outlet: Plug the cooker directly into a known-good outlet without an extension cord or power strip.
• Inspect internal fuse (advanced): With the unit unplugged, remove the bottom cover. Locate the inline or board-mounted fuse near the power entry. Test it with a multimeter; replace only with the same type and rating if blown.
• Check internal connectors: Ensure the AC input wires and connectors from the power cord to the control board are firmly seated.
• Board failure: If the fuse is intact and power still does not reach the control board (no standby voltage), the main PCB is likely defective and should be replaced.

Warning: Mains voltage is hazardous. If you are not trained in electrical safety, limit yourself to external checks and contact a professional for internal diagnostics.
