Multicooker powers on but will not heat in any mode (no warmth on heating plate).

Safety first: Unplug the cooker and allow it to cool. Heating circuit work involves dangerous voltages.

• Confirm symptom: Select Sauté or Brown mode and let it run for several minutes. If the inner pot remains completely cold, proceed with inspection.
• Access base: Remove the bottom cover to expose the heating element and wiring.
• Check connections: Inspect the two main heater terminals for loose or burned spade connectors. Reseat or replace connectors as needed.
• Continuity test (advanced): With a multimeter, measure resistance across the heater terminals. An open reading indicates a failed element.
• Board check: Inspect the heater relay/triac area on the main board for burn marks or cracked solder joints.
• Replacement: Replace the main heating element ring if open or visibly damaged. If the element is good but still no heat, the main control board (heater driver) likely needs replacement.
