Possible Causes

Open-circuit NTC sensor, Broken sensor wiring, Loose sensor connector at control board, Damaged sensor probe from impact or cleaning

How to Fix / Troubleshooting

Safety: Disconnect power before accessing the sensor or control board.

  • 1. Confirm error: Note if the error appears immediately on power-up or only when starting a heating mode. Persistent sensor errors usually indicate an open sensor.
  • 2. Locate sensor: Identify the metal probe inside the cavity (rear or top). Remove its mounting screws and gently pull it forward to access wiring.
  • 3. Test continuity: Disconnect the sensor connector and measure resistance at room temperature. An infinite reading (OL) indicates an open sensor.
  • 4. Inspect harness: Follow the sensor wires to the control board, checking for cuts, burns, or pinched sections.
  • 5. Reseat connector: At the control board, unplug and replug the sensor connector to ensure good contact.
  • 6. Replace sensor: If open or physically damaged, install a new Panasonic-compatible NTC sensor and route wiring as originally installed.
