Type your Amana serial number below to get the month and year it was built. 1 documented Amana serial format, covering 1980 to today.
Amana heating and cooling equipment is built by Goodman (now Daikin) and shares its serial format.
The serial number is on the metal rating plate. On a furnace it is usually inside the front door on the side wall; on an outdoor AC or heat pump it is on the back or side of the cabinet, near the refrigerant lines.
Type the Amana serial exactly as printed. Spaces, dashes and lowercase are all fine.

Where to find the serial on a Amana
- Gas furnace: open the front door. The rating plate is on the inside side wall, usually near the top.
- Outdoor AC or heat pump: a metal or foil plate on the back or side of the cabinet, near where the copper lines enter.
- Mini-split: on the side of the outdoor unit, and on the indoor head behind the front flap or on its right side.
- Photograph the plate rather than copying it by hand. Misreading 0 for O, 1 for I or 5 for S is the most common reason a lookup fails.
Same serial format
These brands come off the same lines and decode identically:
Is your Amana showing an error code?
Age tells you where the unit sits in its life. The fault code tells you what is wrong right now. We have 40 Amana codes, each quoted from the manufacturer's own manual.
HVAC Code Lookup publishes these decoding rules from public industry references, not from Amana. If the rating plate prints an explicit manufacture date, trust the plate over any decoder.
