Thanks. I saw the change in flapper operation but not sure that is the posters problem. He says the cold air is coming from heater ducts and not the vent so will assume he knows the difference and that's what is happening.

I'd never given much thought to airflow inside the box on early units. Question is as much for my education as his. I know the 51 thru maybe 53 or maybe even 54 was as described. 55-6 was different in that the core was angled and air flow was one pass thru full core. Just never paid much attention to the 22-23's.
