Kenmore refrigerators are made for Sears by a variety of other appliance manufacturers, including Whirlpool, LG and Frigidaire. To determine the manufacturer, look at the first three or four digits of the refrigerator's model number. The prefix will correspond to a specific manufacturer; for example, Whirlpool-made products usually start with the prefix 198 or 106.
As a department store, Sears does not build any of its own appliances, hence the need to contract to other companies. Kenmore products are in 60 percent of American homes, according to Daily Finance. Models labeled "Kenmore" may differ in price from products labeled "Whirlpool," even if they were made by Whirlpool. Sometimes, both brands can be made by a different company, as in the case of Kenmore and Maytag washing machines. Both appliances are made by Samsung.
