Ok, a little update... I forgot to mention it's a Coleman Mach (Probably Mach III, not sure at the moment).
I was looking at some parts views, and I see the fan motor only runs the condenser fan and the blower fan. The compressor is it's own little unit (bigger cylinder) , attached to what I think is the dryer (a small cylinder).
I'll try to get some time tonight to double check if the compressor is actually firing up. But either way, if it's a freon leak or if it's a compressor electrical, it might not be fixable.
Still open to opinions & diagnostic ideas though! 🙂
