Display shows H1 and the fridge compartment is excessively cold or shows signs of freezing food.

Safety: Unplug the appliance before removing internal covers.

Steps:

• 1. Check temperature setting: Ensure the set temperature is not at the coldest setting. Adjust to a mid-range and monitor.
• 2. Inspect sensor placement: Locate the fridge NTC sensor behind the liner or near the air outlet. Ensure it is not in direct airflow from the freezer duct, which can cause it to read too cold.
• 3. Test the sensor: Measure resistance at known temperature. A shorted sensor (very low resistance) will cause overcooling and H1. Replace if readings are abnormal.
• 4. Replace sensor if needed: Install a new CDA fridge compartment NTC sensor and secure it away from direct cold air streams.
• 5. PCB check: If the sensor is correct but the compressor runs almost constantly, the main PCB relay may be stuck closed. This requires PCB replacement by a technician.

Tip: Avoid blocking air vents with food items, as this can also cause uneven cooling and sensor misreadings.
