How Whirlpool Serial Numbers Work
Whirlpool Corporation is the world's largest home appliance manufacturer, headquartered in Benton Harbor, Michigan. Founded in 1911, Whirlpool produces appliances under its own name and owns KitchenAid, Maytag, Amana (appliances), JennAir, and several other brands. All of these brands use the same serial number date-encoding system.
The Whirlpool serial number format is unique because it uses letters for both the year and month, creating a compact but powerful encoding system. The second character (position 2) encodes the year using a letter sequence that started at F=1996. The third character encodes the month using letters A through M (skipping I).
The year letter sequence skips letters I, O, Q, and U to avoid confusion with numbers 1, 0, 9, and 0. The sequence cycles approximately every 20 years, which means some letter values repeat. For example, "F" could mean 1996 or 2017. To determine which cycle applies, consider the appliance's apparent age and condition.
The month letter sequence maps as follows: A=January, B=February, C=March, D=April, E=May, F=June, G=July, H=August, J=September (skipping I), K=October, L=November, M=December.
This same encoding system is used by KitchenAid, Maytag, Amana appliances, JennAir, and other Whirlpool subsidiaries. If you have any of these brands, this decoder will work for your unit.

Why Decode Your Whirlpool Serial Number?
Knowing your Whirlpool appliance's age matters for:
Extended Warranty Decisions: Whirlpool offers standard 1-year limited warranties. After that, purchasing a home warranty or extended warranty depends heavily on the appliance's age. Units over 8 years old may not qualify.
Major Repair Decisions: When a refrigerator compressor or washing machine motor fails, the repair vs. replace calculation depends on the appliance's age. Repairs on units over 10 years old rarely make financial sense.
Home Sale Disclosures: Buyers expect to know the age of major appliances. The serial number decode gives you precise manufacture date information for disclosure documents.
Energy Star Upgrades: Whirlpool has made significant efficiency improvements in recent years. Knowing your unit's age helps quantify potential savings from upgrading to current Energy Star models.
Parts Sourcing: Whirlpool maintains parts availability for about 7-10 years after discontinuing a model. Knowing your unit's age helps predict parts availability for repairs.
💡 Pro Tips
KitchenAid, Maytag, and Amana appliances all use the exact same serial number format as Whirlpool. If you have one of these brands, you can use this decoder or visit their dedicated pages. One common confusion: the Amana appliance brand (Whirlpool) is completely separate from the Amana HVAC brand (Goodman/Daikin). Always check your brand carefully before selecting.
Frequently Asked Questions
What does position 2 "X" mean in a Whirlpool serial number?
"X" in position 2 represents the year 2010 (first cycle) or 2030 (if applicable). For most appliances in service today, X = 2010.
Do KitchenAid and Maytag use the same format?
Yes. All Whirlpool Corporation brands — KitchenAid, Maytag, Amana appliances, JennAir — use the same serial number year/month encoding. This decoder works for all of them.
How long should a Whirlpool refrigerator last?
Whirlpool refrigerators typically last 10-18 years. French door and side-by-side models may have shorter lifespans (10-14 years) due to more complex mechanisms.
My Whirlpool washer serial starts with "C" — what year is that?
"C" in position 2 represents 2014. So a Whirlpool washer with a serial starting with "XC..." was manufactured in 2014. Check position 3 for the month.
