Thermoelectric (Peltier) Vinotemp wine cooler is barely cooling; only a few degrees below room temperature.

Safety first: Unplug the unit before disassembling the Peltier assembly. Heat sinks can have sharp fins.

Steps to improve thermoelectric cooling:

• 1. Clean heat sinks: Remove covers to access the internal and external aluminum heat sinks. Use compressed air or a soft brush to remove dust.
• 2. Check fans: Verify that both the interior and exterior fans run when the unit is on. Replace any non-functioning fan motors.
• 3. Inspect Peltier module: Check for signs of overheating or cracking. Measure resistance; replace if open or shorted.
• 4. Reapply thermal compound: When replacing the module, clean old thermal paste from the heat sink surfaces and apply a thin, even layer of new thermal compound to ensure good heat transfer.
