Hey, I kinda have the same problem. I have a 75 OL with the original AC only my compressor comes on just not the fan. Maybe we could combine parts and share the AC
Just kidding. Could be a bad relay or corroded connections. At least that is what I have been told on thid forum. They don't make Armstrongs anymore and parts are hard to come by. Granger sells fan motors and relays and such. If you have a charge in the system (meaning there is freon) that usually indicates that you don't have a leak. I'm gonna start working on mine soon I will let you know what I find. If I decide to scrap the unit I will probably put it up for sale for parts etc. Rob
