Multicooker powers on but does not heat in any mode; timer counts down but food remains cold.

Safety first: Unplug and allow the cooker to cool. Heating circuits carry mains voltage.

• Confirm symptom: Start a high-heat mode (e.g., Fry) and check after 5–10 minutes. If the inner pot is still cold, proceed.
• Inspect heater wiring: Access the bottom and verify that the heater terminals are firmly connected and not oxidized.
• Measure heater resistance: Use a multimeter to check the heating element. Infinite or very high resistance indicates a failing element that may still pass minimal current but not heat properly.
• Check thermal fuse: Test continuity of the thermal fuse in series with the heater. Replace if open.
• Control board output: If the heater and fuse are good, the switching device (triac/relay) on the main board is likely faulty. Replace the main control board.
