Subzero – An Innovative Company

The Sub-Zero brand has been a leader of innovation for over sixty years. It all began in 1943, with a man named Westye Bakke, when he put together the very first ‘freestanding’ freezer in his Madison home. A budding innovator found itself in the hands of an able businessman with the kind of keen observation of the refrigeration market that allowed him to anticipate the trends to build towards them, and two years later, Bakke founded Sub-Zero Freezer Company in an old garage.

The leading manufacturer of built-in home refrigerators came from the modesty of basements and garages, and that pioneering spirit has served Sub-Zero well in the sixty-some years since its inception.

The 50s saw the company innovating the market by creating their first built-in refrigerator designed to blend in with the surrounding furniture of the kitchen, such as cabinets and counters. Their award winning catalogue now includes the 500 Series, the versatile 600 series, the new 700 series and the 200 series of models available for undercounter installation.

Sub-Zero’s aforementioned ‘dual refrigeration’ system has become another hallmark of the company, utilizing two unique cooling systems designed to preserve food with separated self-contained processes working in tandem. These innovations allow Sub-Zero’s refrigeration systems to blend into any nook and cranny of your kitchen, including cabinets and drawers.

Sub-Zero PRO 48 Refrigerator Line

The company advertises itself as being the most technologically advanced and aesthetically stylish refrigeration manufacturer working today, and its current line of refrigerators reflect that mission statement. The PRO 48 line of refrigerators are one hundred percent steel appliances complete with a sculpted metal dual refrigeration system for the longevity and reliability of the cooling system. This line is malleable as both a freestanding refrigerator or a built-in fridge, and its dual refrigeration system compromises three evaporators and two compressors which help to keep food odors contained. The PRO 48 line comes with digitized displays and touch controls outfitted with microprocessors and an interior control panel, and an advanced hinge design that’s a part of Sub-Zero’s ‘auto close’ system to ease the opening and closing of refrigerator doors. The lines comes averaged with an annual energy use of roughly six hundred and ninety one kilowatts, and ships at eight hundred and sixty pounds.


Sub-Zero Built-in Refrigerators

Sub-Zero also offers a built in refrigerator line which includes freezers and combination refrigerators/freezers, and particular models come manufactured with glass or French doors for the homeowner who wants to accent their refrigeration system with a unique touch. ‘Over-and-under’ built-in refrigerators come equipped with low freezers and ice makers, grilles, hinges, while side-by-side built in refrigeration systems offer internal chilled water and ice dispensers inside. Both models come manufactured with a water tank, air purification and water filtration systems, well-lit interior lighting and even informational cards gauging the freshness of foods. Side-by-side build in refrigerators are sold in ‘classic stainless’ and overlay models, and Sub-Zero models carry UL approval for both US and Canada sales.


Despite the company’s standards, there are several common problems associated with Sub-Zero refrigerators. Side-by-side systems have been known to show difficulties with their digitized displays, as well as unwanted water build up and runoff. The ice maker is somewhat difficult to adjust, and, as with other Sub-Zero units, the interior refrigerator lighting is subject to the common problems and complications of most other electrical appliances.

Sub-Zero’s innovative use of water filtration systems is also prone to causing complications in the refrigeration or freezer unit. For Sub-Zero appliance repair and Sub-Zero refrigerator repair it’s recommended that homeowners purchase the Factory Certified installer option on all Sub-Zero products to both ensure that a liable professional can be held responsible for proper installation and that this same professional can be contacted if further repairs are needed.

The majority of problems associated with Sub-Zero refrigerators are either the fault of a manufacturer error – in which case the appliance can be replaced within a full year of purchase, or the fault of the homeowner in the event of an improper installation. Sub-Zero appliance repairs and Sub-Zero refrigerator repairs are covered under the given warranty.

The advanced technology utilized in Sub-Zero refrigeration systems can create a host of new problems that wouldn’t normally occur in a standard freestanding refrigerator. One of the leading troublemakers in Sub-Zero refrigerators comes from the coils behind the grill, which is vulnerable to clogging with dust and other debris. Many consumers also experience problems and malfunctions related to the coils overheating, and it’s recommended that consumers experiencing display errors and other related refrigeration problems vacuum, clean or cool the coil after removing the grill itself.

Additional Sub-Zero Refrigerator Troubleshooting Tips

Many of the problems consumers have in working their Sub-Zero refrigerator can be solved by consulting the instruction manual, including questions on how to adjust the ice maker, monitor the temperature of the fridge and freezer, and reset the digitized readouts in case of error. The vast majority of the time, Sub-Zero’s Factory Certified installer warranty should only be called upon in cases of a damaged product or appliance, as most errors are user errors that can be solved with proper directions and discretion.

Sub-Zero refrigeration systems are an innovative take on the common refrigerator, and as such, might require different handling than many consumers are used to. Sub-Zero offers a toll free customer service line should the manual be insufficient or the directions confusing, and it’s recommended that all problems be screened for simple solutions before paying for any drastic repairs.
