42" Classic French Door Refrigerator/Freezer
THE FRENCH DOOR THAT DOES MORE
It’s no wonder the Sub-Zero 42” French door refrigerator/freezer has quickly become so popular. It’s the widest over-and-under, and even offers 15% more refrigerator storage than 42” side-by-side models. That means easier access to more of the fresh food you reach for most regularly, and with a two-column shelving system, you’ll have more flexibility for storing taller bottles and containers too.
Dual refrigeration ® provides the ideal humid yet chilly conditions for fresh foods, along with dry, frigid air for frozen and convenience foods. An advanced air purification system scrubs the air of ethylene gas, bacteria, mold and viruses. Easy-to-use controls, magnetic door seals and a microprocessor add to the powerful preservation package. And the water filtration system reduces contaminants and chlorine taste and odors when purifying water or ice. Capacity is a generous 17.9 cu. ft. refrigerator, 6.3 cu. ft. freezer. less

Air purification system fights spoilage, odors
Many fresh foods emit ethylene gas, a natural compound that hastens spoilage. Sub-Zero's classic refrigerators come with an anti-microbial air purification system (based on technology developed by NASA) that scrubs the air of ethylene, as well as mold, viruses and bacteria, every 20 minutes.
Low-temperature/high-humidity storage zones
Crispers and deli drawers are strategically located near the evaporator to maintain temperatures a few degrees cooler than the rest of the unit. Drawers are sealed to lock in humidity and ensure freshness.
Helpful freshness cardsDifferent foods require different storage procedures. That's why, inside each refrigerator, you'll find "freshness cards" that provide easy-to-follow tips for ensuring maximum food preservation.
Magnetic door seal system locks in cold air
One-piece construction, extra-heavy insulation and magnetic gaskets around every door lock in cold air. Seals are so secure that even after power outages of multiple days, owners report no thawing of their frozen foods!
Adjustable shelves for maximum convenience
Food comes in all shapes and sizes, and the interior design of Sub-Zero refrigerators and freezers accommodates that diversity. Main shelves, door shelves, even dividers in drawers adjust to allow the most convenient configuration possible.
The deli is open!
A soft-close deli drawer that spans the width of the refrigerator's interior provides ample room for packages and trays of meats, cheeses and more. Plastic dividers can be arranged for extra organization, or removed altogether.

Dual refrigeration keeps food fresher
This technology pioneered by Sub-Zero features two separate cooling systems. Fresh food stays fresher in the cool, moist air of the refrigerator, while frigid, dry air prevents frost and freezer burn in the freezer – optimum preservation conditions for each type of food.
Microprocessor control guarantees peak performance
The state-of-the-art microprocessor preserves your food by adjusting to your individual climate and schedule. It continuously monitors each section of your Sub-Zero for pinpoint climate control, so foods are kept at their ideal temperature, varying by only one degree of your set point. Also lets you finesse your lighting and cooling fan, tells you if your door is ajar, and defrosts when it's most convenient for you.
Over-and-under refrigerator/freezer storage
Classic over-and-under units feature easy-access refrigerator storage above a full-extension, roll-out freezer drawer containing two-tier wire baskets.
Designed to reduce contaminants and chlorine taste and odors when filtering water for ice, this low-maintenance system uses a filter built to last 1 year or 750 gallons. Replacement is fast and easy.
Automatic ice maker with "max ice" feature
Provides crescent-shaped ice cubes and includes a "max ice" feature capable of increasing ice production by an average of 30 percent for a 24-hour period – just the boost you need for parties and holidays.
Maximum capacity in a 42" French door model
For those kitchens where storage space is at a premium, the Sub-Zero 42" over-and-under with French door provides nearly 25 cubic feet of combined refrigerator and freezer capacity. That's more usable space than any other classic French door model, with a refrigerator that's 12% roomier than a Sub-Zero 42" side-by-side model.
Two-column shelving for customized storage
The 42" over-and-under with French door is the only Sub-Zero refrigerator with shelving that is split into two columns for maximum flexibility. Line up two half shelves to form a full-width shelf, or stagger their positions to customize storage for tall or short items.
