THE FRENCH DOOR THAT DOES MORE It’s no wonder the Sub-Zero 42” French door refrigerator/freezer has quickly become one of our most popular. It’s the widest over-and-under we make, and even offers 15% more refrigerator storage than our 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 18.3 cu. ft. refrigerator, 6.4 cu. ft. freezer.

  • The condenser coils require regular cleaning by vacuuming to remove dust and lint from the condenser area. If you have any furry, four-legged friends roaming the house, plan on cleaning more frequently.

42" Built-In French Door Refrigerator- Stainless Steel - Model: BI-42UFD/S


Features

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.

Dual refrigeration keeps food fresher: This technology pioneered by Sub-Zero features separate compressors and cooling systems for the refrigerator and freezer. Fresh food stays fresher in cool, moist air on one side, while frigid, dry air prevents frost and freezer burn on the other — optimum preservation conditions for each type of food.

Air purification system fights spoilage, odors:

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

Microprocessor control guarantees peak performance:

Our 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.

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.

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.

Water-filtration system:

Designed to reduce contaminants and chlorine taste and odors when purifying water or ice, this low-maintenance system uses a filter built to last 1 year or 750 gallons. Replacement is fast and easy.

Helpful freshness cards: Different foods require different storage procedures. That's why, inside each refrigerator, we include "freshness cards" that provide easy-to-follow tips for ensuring maximum food preservation.

Rigorously tested to ensure dependability:

Built with superior-quality materials, Wolf products are designed to last a minimum of 20 years under far heavier use than any home cook will ever subject them to. To ensure reliability, engineers stress-test our designs under laboratory conditions that simulate years of use. Major components are tested and subjected to extreme stresses prior to going into the final design of the unit, and every major function of every completed product is tested before shipping.

Exceptional 24/7 customer support:

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

"Soft bright" interior lighting:

Evenly distributed interior lighting – powered by specially designed 40-watt appliance bulbs in the refrigerator and freezer – illuminates food in a soft, pleasing manner, making even those cornichons back in the corner easy to spot.

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.

Magnetic door seal system locks in cold air:

One-piece construction, extra-heavy insulation and magnetic gaskets around every door lock in cold air. Our seals are so secure that even after power outages of multiple days, owners report no thawing of their frozen foods!

Automatic ice maker with “max ice” feature:

High-efficiency unit 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.

Adjustable shelves for maximum convenience:

Food comes in all shapes and sizes, and the interior design of our refrigerators and freezers accommodates that diversity. Main shelves, door shelves, even dividers in drawers adjust to allow the most convenient configuration possible.
