⚡ Open Maytag DecoderMaytag equipment typically displays the model and serial data tag on a manufacturer rating plate. Look for a label that lists "Model" and "Serial" and check common locations by product type: inside doors, behind access panels, on the back panel, or near the compressor / condenser area.
Maytag is an American appliance brand with over a century of history. A critical event for serial number decoding is Whirlpool Corporation's acquisition of Maytag in 2006. This ownership change resulted in a format shift: Maytag appliances manufactured after 2006 use the Whirlpool serial format, while older units used the original Maytag encoding system.
Post-2006 Maytag (Whirlpool format): Serial numbers from 2006 onward use a single letter to encode the year and a two-digit number to encode the week of manufacture. On a 9-character serial, the year letter is the second character; on a 10-character serial, it is the third. A 30-year repeating cycle is used, so two years may be shown when the year code is ambiguous.
Pre-2006 Maytag (original format): Older Maytag appliances use a different letter-and-number encoding system in which the second and third characters encode the manufacture decade and year, followed by characters encoding the month and production sequence.
When you select Maytag in the decoder, an Era dropdown will appear asking you to choose Pre-2006 or Post-2006. Selecting the correct era is essential for an accurate result.
Selecting the wrong era. This is the most impactful mistake possible with Maytag serial numbers. Applying the pre-2006 decoder to a post-2006 appliance (or vice versa) will produce a completely incorrect manufacture date. If you're unsure, use the appliance's visual design as a guide — digital displays, smooth electronic controls, and stainless steel finishes are characteristic of post-2006 Maytag units.
Confusing Maytag with Maytag-branded Whirlpool products. After 2006, all new Maytag appliances are manufactured by Whirlpool. If your Maytag appliance has a modern design, select Post-2006 with confidence.
Using the model number. Both model and serial numbers are on the data label. For date decoding, always use the serial number — the model number describes the product type and features, not the manufacture date.
