Possible Causes

Any NTC sensor (ambient, evaporator, water temperature) disconnected, Sensor shorted due to moisture, Incorrect sensor type installed, Damaged sensor harness

How to Fix / Troubleshooting

Safety: Unplug the Sencor unit before inspection.

Steps:

  • Identify sensors: Refer to the service manual or internal labeling to locate all NTC sensors (ambient, coil, water tank, etc.).
  • Check connections: One by one, inspect each sensor connector on the main PCB. Ensure they are firmly seated and not swapped between sockets.
  • Inspect for moisture: Look for condensation or water around sensor connectors, especially near the water tank area. Dry thoroughly and apply contact cleaner if needed.
  • Resistance check: Measure each sensor's resistance at room temperature. Any sensor reading open circuit or near zero ohms should be replaced.
  • Replace faulty sensor: Install the correct Sencor sensor assembly for the specific location and model.

Note: If all sensors test correctly, the main PCB's sensor reading circuit may be defective.
