Maytag is a major manufacturer of household appliances. The company's dishwashers, refrigerators, microwaves, washer/dryers and other works have been a mainstay of households for decades. When deciding whether to replace an appliance, age is often a factor: Consumers want to know how much more use they can reasonably expect to get from it. Serial numbers can help determine when a product was made.
Find the serial number. Maytag stamps its appliances with serial numbers in at least one place and sometimes more. In general the serial stickers are kept in spots people don't usually touch. For example, Maytag refrigerators have serial numbers in the upper left corner of the food liner and the upper left side of the crisper pan.
Find the year and month code. Each Maytag serial number contains two letters. These represent the year and month of manufacturing. They should be the ninth and 10th characters of the serial number.
Determine the year and month of manufacturing. The first number represents the year and the second represents the month. For example, a code of HN means the appliance was made in July of 1993. The code does not use all letters of the alphabet, however, and sometimes two different letters can mean the same thing. X and Z, for example, both represent the month of December.
