How to Decode Maytag Serial Numbers
Step-by-step guide to decoding any Maytag HVAC serial number. Learn the Year-Month (YYMM) format, what each digit means, and get instant results with our free decoder tool.
Step 1: Locate the Maytag Label
Find the data plate on your Maytag unit. It's usually on the side panel (outdoor units) or inside the cabinet door (indoor units). The label contains both the model number and serial number.
Step 2: Identify the Serial Number Format
Maytag uses a Year-Month (YYMM) serial number format. Do not confuse the serial number with the model number -- the serial is unique to each unit, while the model identifies the product line.
Step 3: Enter in the Decoder
Type your Maytag model or serial number into HVAC Decoder Pro. Our decoder instantly parses Maytag's encoding format and extracts manufacturing date, capacity, refrigerant type, and SEER rating.
Step 4: Review Your Results
The decoder displays a complete profile: manufacturing date, tonnage, BTU capacity, refrigerant type with phase-out status, SEER rating, and a color-coded condition indicator (Green = Good, Yellow = Aging, Red = Replace Soon).
