Undercounter beverage and wine cooler built into kitchen cabinets

Field pattern: wine cooler or beverage fridge 'too noisy' (normal fan and refrigerant sounds vs vibration and fan contact)

Most noise calls are normal operation: compressor hum, refrigerant gurgle, thermostat clicks and fans that cycle often or run continuously. The real faults are vibration against a cabinet or wall, an unlevel unit, a fan blade hitting frost or a loose part, and a dirty condenser making the unit run long. Sort normal from abnormal before ordering a fan.

Wine cooler or beverage center: frost or ice on the back wall

A light film that comes and goes can be normal on cold-wall units. Thick or growing ice means warm, humid air is getting in (gasket, door not closing, frequent openings), the setpoint is too cold, the unit is in a hot or poorly vented spot, or the defrost function has failed on auto-defrost models.

Wine or beverage cooler temperature swings or display doesn't match a thermometer

Air temperature in any cooler rises and falls as the compressor cycles, during defrost and after door openings; a few degrees is normal and some makers accept about 6-8 F. Measure product temperature, not air, using a probe in a bottle or glass of water for 24 hours, then decide whether there is a real sensor, seal or airflow problem.

Field pattern: thermoelectric wine cooler 'not cold enough' in a warm room or garage (ambient limit, not a failed part)

Thermoelectric units can only pull the cabinet roughly 10-12 °F below the room and most will not go below about 50 °F. Above about 80 °F room temperature they cannot hold wine temperature, and below about 50 °F they cannot keep up either because there is no heater. Boxing a freestanding unit into cabinetry kills its heat sink airflow. Measure the room before condemning the module.
