Multicooker powers on but will not heat in any mode (pressure, sauté, slow cook); timer counts down but food remains uncooked.

Safety first: Unplug the cooker and allow it to cool before opening the base.

• Confirm symptom: Start a sauté or brown program with a small amount of water. If after several minutes the water is still cold and the bottom of the pot is not warming, proceed with checks.
• Access heating element: Remove the bottom cover to expose the circular heating element and its wiring.
• Inspect connections: Look for loose or burned spade connectors on the element. Reseat or replace damaged connectors.
• Test element resistance: Disconnect one lead and measure resistance across the element with a multimeter. A very high or infinite reading indicates a failed element that must be replaced.
• Check thermal fuse: Locate any thermal cutoff in series with the element and test for continuity. Replace if open.
• Control board issues: If the element and fuse test good, the triac or relay on the control board may not be switching power and the board will need replacement.

Warning: Do not bypass the thermal fuse or operate the cooker with exposed wiring.
