Common questions about manuals, registration, and support for this brand.
The serial number tag location varies by model. For all-refrigerator and over/under models, it is typically located near the top door hinge in the refrigerator compartment. For side-by-side models, look near the top door hinge in the freezer compartment.
On most modern Sub-Zero units with a touch control panel, touch the temperature reading you wish to change and use the + or - indicators to adjust it. The recommended settings are typically 3°C (38°F) for the refrigerator and -18°C (0°F) for the freezer.
To ensure efficient operation, Sub-Zero recommends cleaning the condenser every 3 to 6 months. This usually involves vacuuming the condenser area to remove dust and lint obstruction, which helps prevent service issues.
