Wine cooler not cooling (thermoelectric vs compressor)

First identify the type: thermoelectric units (quiet, no compressor) are limited by room temperature and depend on their fans and heat sinks; compressor units depend on a clean condenser and working fans. Many no-cool calls are ventilation, door seal or room temperature problems.

Door seal problems and interior light not working

A worn or poorly seated gasket causes warm cabinets, moisture and long run times. A dead light is usually the bulb/LED, a loose connection or the light switch, which on many units is part of the display board.

Condensation on the glass door or water on the floor

Door sweating is usually humid room air on cold glass, made worse by a leaking gasket, blocked vents or frequent openings. Water on the floor usually means the drip tray is out of place or the defrost drain is clogged.
