42" SUBZERO Built-In French Door Refrigerator/Freezer - BI-42UFD/S/TH

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.

New LED LIGHTING FOR BRIGHTER INTERIOR

See all your fresh foods more clearly and easily. LED lighting is also more energy-efficient - designed to last the life of your refrigerator.

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.

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.

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.

Water-filtration system

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.

Rigorously tested to ensure dependability

Every component of every single Sub-Zero unit is tested in its U.S. manufacturing facilities before assembly, then every completed product is factory-tested for up to 24 hours before shipping. In its labs, components are subjected to electric jolts, violent vibrations and 350° temperature swings, and tested to stand up to at least 20 years of heavy use.

Over-and-under refrigerator/freezer storage

Built-in over-and-under units feature easy-access refrigerator storage above a full-extension, roll-out freezer drawer containing two-tier wire baskets.

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 built-in French door model, with a refrigerator that's 12% roomier than a Sub-Zero 42" side-by-side model.

Air purification system fights spoilage, odors

Many fresh foods emit ethylene gas, a natural compound that hastens spoilage. Sub-Zero's built-in 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.

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.

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.

Helpful freshness cards

Different 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.

Exceptional 24/7 customer support

Whether you're shopping for appliances or have questions about those you already own, the Sub-Zero, Wolf, and Cove Customer Care team has a reputation for service that's as exceptional as its products. They're based in Madison, Wisconsin, just footsteps from the factory, and are standing by to provide expert, friendly, problem-solving support.

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.
