Multicooker powers on but will not heat in any mode (Sauté, Brown, Pressure, or Slow Cook).

Safety first: Unplug the unit and allow it to cool before internal inspection. Only perform electrical tests if qualified.

• Test Sauté mode: With the inner pot in place, select Sauté and wait several minutes. If the pot remains cold, the heater is not energizing.
• Listen for relay click: When starting a heating mode, you should hear a faint click from inside. No click may indicate a failed relay or control board.
• Internal inspection (advanced): Remove the bottom cover and inspect the heater terminals and wiring for loose connections or burns.
• Check thermal fuse: Locate the thermal cutoff attached to the heater or plate. Test for continuity. An open fuse indicates it has blown and must be replaced with the same rating.
• Professional repair: Replacement of the heating element, thermal fuse, or control board should be done by a technician.
