Fridge -2 degrees, constant beeping

Refrigerator -2 degrees, constant beeping - Refrigerator section too cold, overcooling alarm

Samsung · Refrigerators

What does Fridge -2 degrees, constant beeping mean?

The Refrigerator's temperature display shows an abnormally low temperature of -2 degrees (implying Celsius, which is freezing) for the fresh food section. This is accompanied by continuous beeping, likely serving as an alarm for the overcooling condition.

Common Causes

  • Faulty Refrigerator thermistor (temperature sensor) providing incorrect readings
  • Control board malfunction causing excessive cooling
  • Airflow issue diverting too much cold air into the Refrigerator section
  • Refrigerator temperature setting accidentally set too low
