Wine cooler runs continuously and rarely shuts off, even when set temperature appears reached.

Safety: Unplug before cleaning coils or inspecting the rear compartment.

Steps:

• 1. Verify actual temperature: Use a thermometer to confirm whether the cabinet is actually at the setpoint. If not, treat as an insufficient cooling issue.
• 2. Clean condenser and improve ventilation: Remove dust from condenser coils and ensure proper airflow around the unit.
• 3. Inspect door gasket: Replace if leaking. Warm, moist air infiltration forces longer run times.
• 4. Check ambient conditions: If the room is very warm (above 85–90°F), the cooler will run longer. Consider relocating or improving room cooling.
• 5. Sealed system check: If the unit runs continuously but cannot reach setpoint, a sealed system issue (leak or weak compressor) may be present and requires a professional technician.
