Had time to do a bit of testing today John; fan motor is running very slowly. Could still be a bad cap, motor or dry shaft bushings dragging after sitting for a year unused. When the indoor fan motor starts, the initial surge is 3A, then falls to running amp-draw is 1 amp. That leads me to suspect the shaft bushings.
The service manual makes it clear how to follow the trouble-shooting tree.
I was inspecting the mechanics of removing the unit and it appears the unit cannot drop straight down or it will hit the outside metal framework that protects the 6535 from damage, plus that framework is where the dress grill attaches to the MH at the bottom.
More inspecting in the future when I get time. It's a good project for a rainy day, but no rain in the forecast for the next 10 days. Owning a hobby farm, isn't a hobby @ 80 it's work. Dr. wants me to have shoulder replacements, I said nope, just keep giving me those cortizone shots every 4 months to ease the pain and I'm good.
