Alarm for high ambient temperature or installation error, cooling performance reduced

Safety first: Disconnect power before accessing external sensors.

• Check installation location: Ensure the refrigerator is not installed next to ovens, radiators, or in direct sunlight.
• Locate ambient sensor: On some models, this is behind a grille on the cabinet front or rear. Inspect for dirt or damage.
• Clean sensor area: Remove dust and debris that may insulate or heat the sensor.
• Replace sensor if faulty: If the sensor housing is cracked or readings are clearly wrong (e.g., showing very high ambient in a cool room), replace it with an OEM part.
• Monitor operation: After replacement, allow several hours for the system to adapt and re-evaluate performance.
