Hi All,

Most of the newer Trane furnaces I find have the manufacturing date clearly stamped on the label. My decoding chart, which I've put together with the help of many others over the years, says that Trane's dated serial numbers begin in 1971 and that age was initially a number followed by a letter in the serial number. Example: 1C-xxxx = March 1971, 81, 91, 01 (Use common sense to distinguish one decade from the next.). Then, beginning somewhere around 1982 the date of manufacture is stamped on the ID plate.

However, there have still been a few instances when I've had fairly new Trane furnaces where the date was not stamped on the label and I was left scratching my head, trying to figure out when the thing was manufactured.

Well, I think I've figured it out. I've been looking closely at the Trane serial numbers for months now and I've noticed that the first digit of the serial number corresponds to the year and that the next to digits correspond to the week of the year. For instance, the last two Trane jobs I did:

Trane XB furnace, Model# TDE1B0809451AA, Serial# 7165RHA1G is stamped that it was manufactured in April 2007

Trane XB furnace, Model# TDE1A060A9361AA, Serial# 6132FD1G is stamped that it was manufactured in March 2006.

So, if you get one of those tricky Trane data labels that doesn't have a date stamp on it, look at those first 3 digits to see if they'll fit within the time period that you suspect the furnace was manufactured.

ONE TEAM - ONE FIGHT!!!

Mike
