Bryant Plus90 Parts List?

[roddhall]

Any idea where I can get a parts list for my Bryant Plus90 Furnace? Model Number [FONT='Calibri','sans-serif']398AAZ036080, Product Number [FONT='Calibri','sans-serif']398AAZ036080AAKA, Series A, Serial Number [FONT='Calibri','sans-serif']2891A03716. I've begged Bryant and Carrier, but they won't give a parts list to anyone who isn't a certified technician. So if I think I need to replace a part, I'm reduced to dis-assembling the furnace and hoping the old part has a number printed on it. Some do, some don't.[/font][/font][/font]
