Sub-Zero manufactures two series of built-in refrigeration as well as wine storage and undercounter units. Each refrigerator model usually comes in two variations, namely a stainless steel exterior or a customizable exterior in an overlay version. The latter option allows the buyer to install kitchen cabinet panels on the door(s) to match with the rest of the kitchen. Its refrigerators are designed with a 24-inch (61 cm) depth and can be installed flush with kitchen cabinets of the same standard depth to provide an integrated look. This kind of built-in refrigerator is usually wider than normal to compensate for the shallower depth in order to maintain acceptable storage volume.
The Sub-Zero 424 Wine Cooler has held virtually the same design since the early 1990s. It is the only under-counter wine cooler in its class to be able to keep wine as low as 38 °F (3 °C). It has two temperature zones and can be connected to a house alarm.
A Sub-Zero refrigerator is heavier than most refrigerators offered by GE, Frigidaire, or LG. An average refrigerator weighs 250–300 pounds (110–140 kg), but a Sub-Zero can weigh as much as 800 pounds (360 kg) and can require four delivery people to move the refrigerator unit into a kitchen, while most refrigerators usually only require two delivery people. Also, a typical Sub-Zero unit is taller than the basic home refrigerator. Most Sub-Zero full-size models are 84 inches (2.1 m) tall and 48 inches (120 cm) wide.
The company currently has production facilities in Madison, Wisconsin; Phoenix, Arizona; Richmond, Kentucky; and Fitchburg, Wisconsin. Along with many other major prestige appliance brands, Sub-Zero follows a practice of restricting dissemination of the prices of their refrigerators. Their dealers are strictly vetted and must closely follow advertising and pricing procedures supplied by the manufacturer in order maintain the ability to distribute their products.
Like most household brands of refrigeration, Sub-Zero refrigerators require a small amount of maintenance. The Condenser of the Sub-Zero refrigerator should be vacuumed and cleared of any obstructing dust annually. Dust can accumulate on the condenser and cause inefficiencies in the sealed system. Many Sub-Zero's refrigerators are equipped with CPU boards that notify the consumer when actions should be taken to clean the condenser.

What if my Sub-Zero product is flashing “Vacuum Condenser” or “Service”?
If your unit is flashing “Vacuum Condenser” or “Service” the main control board has registered unusually long run times on your product.
If this occurs, one cause can be a dirty condenser. The condenser should be cleaned regularly. If it has been more than six months since the condenser has been vacuumed; clean immediately, then turn your unit off and back on.
By cycling off your unit this message should be cleared. If your condenser is already clean or the “Vacuum Condenser” or “Service” message returns, call for service, there is a problem.
Note: For help with cleaning the condenser on your specific unit, refer to your owner’s manual or call Sub-Zero Customer Care 800-222-7820 or visitSubzero.com.
What if the electronic controls on my Sub-Zero/Wolf/Asko product are not responding?
On rare occasions electronics can lock up. We have all experienced this with our computers. If this occurs it can often be resolved by cycling off (re-booting) your unit at your house electrical panel. Cycle off your circuit breaker to the unit; then cycle back on to re-boot.
What information should I provide when calling for service?
In addition to address and phone number, it is a good idea to have model/serial numbers and date of purchase of the Sub-Zero/Wolf/Asko product needing assistance. Also provide the article number for Asko products.
Why is factory service better than non factory service:
Factory trained servicers get hands on training on all Sub-Zero/Wolf products the first year the products are released.
Factory servicers work on Sub-Zero/Wolf products for two years while the products are under the manufacturer’s warranty. This allows the factory servicers to be extremely knowledgeable about your Sub-Zero/Wolf product.
If your product needs a part to resolve your service problem, that part may have an extended part warranty. Your factory certified servicer will know this and make sure you get any warranty help that is available on your product.
