Possible Causes
Open or damaged lid temperature sensor, Loose lid sensor connector, Broken wiring in lid hinge, Failed main control board
How to Fix / Troubleshooting
Safety first: Unplug the cooker before working on the lid.
- Check lid fitment: Ensure you are using the correct lid for the model and that it is properly installed.
- Inspect lid wiring/connector: On models with a detachable lid connector, verify it is fully seated and free of corrosion or debris. On hinged lids, visually inspect the hinge area for damaged wiring.
- Reseat connectors: If accessible, reseat the lid sensor connector on the main control board.
- Replace sensor or lid: If wiring and connectors appear intact but E4 persists, replace the lid temperature sensor assembly or the complete lid assembly depending on design. If the error remains after replacement, the main control board is likely at fault.
