Possible Causes

Failed lid NTC sensor, Broken sensor wiring in lid hinge, Connector damage between lid and main body, Control board sensor channel failure

How to Fix / Troubleshooting

Safety first: Unplug the cooker before working near the hinge or lid wiring.

  • Inspect hinge area: On ETA models with wired lids, gently move the lid and observe the cable bundle at the hinge. Look for cracked insulation or pinched wires.
  • Check lid connector: Some models have a plug connection between lid and body. Ensure it is fully seated and free of corrosion.
  • Power reset: After reseating connectors, unplug for 10 minutes, then test again.

When to call a technician: Replacing the lid sensor or repairing hinge wiring requires disassembly of the lid and should be done by a professional to avoid damaging the pressure system.
