Wine cooler runs constantly but does not reach the set temperature; interior is cool but not cold enough.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Unplug the unit before cleaning or fan inspection.
- Clean condenser: Access the rear of the unit and brush/vacuum dust from the condenser coils. Good airflow is critical for Hisense compressor-based wine coolers.
- Check condenser fan: Ensure the fan runs whenever the compressor is on. Replace the fan motor if it is slow, noisy, or not running.
- Verify door seal: Inspect the door gasket for gaps or tears that allow warm air in, forcing the unit to run continuously.
- Monitor frost pattern: Remove the inner rear panel and observe the evaporator after 15–20 minutes of running. A healthy system will have an even frost pattern across most of the coil. Frost only on a small section often indicates low refrigerant.
If cleaning and fan replacement do not restore performance and the frost pattern is abnormal, a sealed-system leak or weak compressor is likely. This must be diagnosed and repaired by a refrigeration technician.
