• Locate ambient sensor: Typically near the air intake grille or on a bracket inside the front housing.
• Check connection: Ensure the sensor plug is fully seated on the main PCB. Reseat it to ensure good contact.
• Inspect wiring: Look for any visible breaks or damage in the sensor wires.
• Replace sensor: If the sensor is open (infinite resistance) or physically damaged, replace it with a Hisense-compatible ambient temperature sensor.
