If the below is correct your is 1983… I guess!

Serial # - W4C210737

“Trane: Keeps switching the code. Beginning in 1971, age is a number followed by a
letter in the serial number. Example: 1C-xxxx = March 1971, etc…
1980, 1981, 1982 the year is a letter in the 7th place. O = 80, T = 81, U = 82
Beginning 1983 a letter was used in the first position to designate the year followed by
the week. W = 83, X = 84, Y = 85, S = 86, B = 87, C = 88, D = 89, E = 90, F = 91, G =
92, H = 93, J = 94, K = 95, L = 96, M = 97, N = 98, P = 99, R = 00, Z = 01. Example:
B50632891 = Dec 87
(Beginning around 1987 the date of manufacturer is stamped on the ID plate most of the
Beginning in 2002 the first digit of the serial number is the year followed by the week.
Example: 7165RHAIG equals the 16th week of 2007.
(Date of manufacture is on the data plate most of the time, but not always)
Beginning in 1987 they began using alpha codes in their serial numbers to determine year
of manufacture. They began with the letter B and skipped a couple of letters during the
years… The first letter of the serial number gives the year of manufacture:”

GE sold their central HVAC division to Trane in 1982.

If it says GE, it’s 1982 or earlier.

Unless your talking window or in wall units. In which, GE still makes those.

Ian … Rooftop unit.

My Carrier Bluebook showed GE models in 1983-1984 ???

So my best guess is 37th week of 1967, 1977, 1987
INachi members, great info on their site :slight_smile:

Mr. Lewis has it. Manufactured in 1983.

Dan if you go to the Trane section of your bluebook you may find the model number BWD you are looking for (those units are listed under Trane in Preston’s guide). Trane bought GE in 1982 (as Ian stated) and manufactured GE but left the GE data plate on those units for several years.

**an Appliance **

The manufacturing date and year is coded into the serial number (not the model number) of the appliance. Our serial numbers begin with two letters. The first letter identifies the month and the second letter identifies the year. The corresponding letters, months, and years are below. For example, if the serial number begins with the letters “FJ,” the appliance was made in March of 1952

The info you gave is different.

Ah. I was never sure if or how long they kept the GE nameplates during the transition. It certainly makes sense that it wouldn’t be a hard cutoff.

Thanks guys for the help … Peter the tag was faded but 2 different people looked at it and agreed on the numbers.

The building itself was built in 1975 … 1952 would be 23 yrs before that ??

I think we’re go with 1983 +/-


Sorry about that!!
