How to Fix / Troubleshooting
Safety first: Unplug the cooker and allow it to cool completely before any internal inspection. Only perform electrical tests if you are qualified.
- Check basic heating: Attempt to use Sauté mode. If the inner pot remains cold and F2 appears, the heater circuit is likely open.
- Visual inspection (advanced): Remove the bottom cover to access the heater and wiring. Look for burned connectors, broken wires, or discoloration around the heater terminals.
- Test continuity (advanced): Using a multimeter (with the unit unplugged), check continuity across the heating element and thermal fuse. An open reading indicates a failed component.
- Do not bypass thermal fuse: Never short across a blown thermal fuse; it is a critical safety device.
- Professional repair: Replacement of the heater, thermal fuse, or control board should be done by a qualified technician.
