The 427R pairs two wine storage zones with a third zone of refrigerator storage drawers underneath, from Sub-Zero’s discontinued 400 Series. Because the lower drawers hold food rather than wine, keep a thermometer in that section and hold it near 40°F, the FDA’s recommended maximum for refrigerated food.
Condensation forming on the inside face of the door, and one storage zone running warmer or cooler than it’s set to, are the wine-side issues reported most on a 427R. Separately, the refrigerator drawer no longer running square on its slides — so it doesn’t seal when pushed home — is a mechanical wear point worth checking if that zone stops holding temperature.
Key Features
- Wine storage unit with refrigeration drawers, carrying a third temperature zone of refrigerator storage drawers below two wine zones
- 400 Series wine storage generation, no longer produced
- OEM parts generally still available to order, though legacy items take longer to arrive than parts for a current model, specific to the 427R.
