Timer counts down but the multicooker does not heat; food remains uncooked.

Safety first: Unplug the cooker before any internal inspection.

• Check for warmth: After running a program for several minutes, carefully feel the exterior near the base. If it is completely cool, the element is not heating.
• Listen for relay click: Start a program and listen for a click from inside. No click may indicate a failed relay or control signal.
• Internal wiring check (advanced): Remove the bottom cover and inspect the heavy wires from the control board to the heating plate for breaks or burned connectors.
• Do not bypass safety devices: If the thermal cutoff is open, it indicates an overheat event. It must be replaced, not bypassed.
• Professional repair: Heating element or control board replacement should be performed by a qualified technician.
