Rheem furnace problem.

Hi folks. I have a Rheem RGDD-06NC-ER forced-air furnace. It's been a good unit for many years.

This year, It's not blowing as warm as it usually does. There is good air flow through the system, but the temperature is much lower than it has been in the past. Filters are good, the unit works fine otherwise.

Any suggestions on what to search for?

Also, can someone point me to a source for a copy of the schematic for this unit? the original is pretty brown and brittle, and some pieces of the paper are missing. And/or a repair manual would be great.

Rheem is a pain in the butt when it comes to diagrams, parts lists, etc. unless you are a Rheem dealer.
How do the flames look? Any return ducts broken & maybe pulling unusually cool air from an uncondtioned space?
