Sub-Zero Refrigerator Running Constantly
Long run times need to be considered together with actual cooling performance. A refrigerator recovering after heavy use is different from one that runs continuously while temperatures rise.
What to check first
- Confirm doors and drawers close completely.
- Note recent warm groceries, frequent opening or unusually warm room conditions.
- Check when accessible condenser maintenance was last completed according to the model guide.
What the observations mean
Sound alone cannot show whether the unit is working correctly. Record whether the compartments hold their normal temperatures. Airflow restrictions, door leakage and cooling-system faults can all increase workload, but the right repair depends on inspection and measurements.
Before you request service
Tell us how long you have noticed the change, whether the sound ever stops and whether food temperatures have changed. Do not block ventilation openings or cover grilles in an attempt to reduce noise.
Have the full model number, your city and ZIP code ready. Describe when the issue began and whether it is constant or intermittent. Avoid removing appliance panels, handling wiring or opening refrigerant lines; those checks belong to a qualified technician.
