Maytag serial number decoding depends entirely on whether the unit was built before or after the 2006 Whirlpool acquisition. Legacy Maytag units (Pre-2006) feature a serial number ending in two letters: the first is the year, and the second is the month (e.g., 'UY' = November 1998). Modern Maytag units (Post-2006) follow Whirlpool’s 9-digit convention, where the 2nd character indicates the manufacturing year.
Pre-2006 (Legacy Maytag)
For decades, Maytag used a simple two-letter suffix system to date their units. This applies to the famous "Dependability" washers and early Neptune front-loaders.
Format: 8–10 digits followed by 2 letters (e.g., 12345678UY)
- Penultimate Letter (Year): A=1977/1989/2001, B=1978/1990/2002... U=1998.
- Last Letter (Month): A=Jan, B=Feb, C=Mar... Y=Nov, Z=Dec. (Note: Maytag skipped some letters to avoid confusion).
Post-2006 (Whirlpool Era)
Whirlpool acquired Maytag for $1.7B in 2006. Since then, the manufacturing has been integrated into Whirlpool’s plants, and the serial formats have been standardized.
Format: 9 Characters (e.g., CY4212345)
- 2nd Character: Year code.
- 3rd & 4th Character: Week code.
The Maytag Brand Family
When you decode a Maytag serial, you are often looking at a unit that shares parts with several other brands. The Maytag "family" of labels includes:
- Admiral: Budget-friendly units, often sold at Home Depot.
- Amana: Value-tier appliances.
- Jenn-Air: Premium kitchen appliances.
- Magic Chef: Many older units were built on Maytag chassis.
- Neptune: The pioneering (and sometimes controversial) front-load washer line.
Maytag Reliability Data
Maytag remains one of the most reliable American brands, with washers averaging a 10-year lifespan. However, the pre-2006 "Newton, Iowa" built units are legendary for lasting 20+ years. Modern Maytag units feature the "10-Year Limited Parts Warranty" on the drive motor and wash basket—a direct nod to their "Dependability" heritage.
