Another Amana furnace-need age

I am also looking for the age of an Amana furnace.

Model GH1050M Ser# BB80200127

Thanks in advance for any help on this.


Preston’s gives me Model # GH105DM (not GH105OM) as manufactured in 1983 with 105,000 BTU’s.

SWEET! Thanks fro the quick response Dave, You are the man!
