Gents (and anyone else),
Cleaning and lubing the fan control switch worked for me. 15 minute time factor.
I had no action, fan or otherwise, from the fan control knob. Searching revealed this thread.
additional searching revealed the below YT video.
Disassembling and cleaning the fan switch with QD electronic contact cleaner, and
lubing with some dielectric grease, has positively resolved all my symptoms.
It has only been an hour, and time will tell, but it beat spending the $754 some cat wants on eBay for a new one.
LIMFACS: The plastic on my control panel is super brittle, be gentle. I used dental picks to ease the switch apart and a brass brush to abrade the contacts.
I have not researched, but wondering if substituting fan control switches between these years is an answer in alot of cases, i suspect yes.
Credit where due: Thank you to youtube's Jim/1Road for the inspiration.
