I guess my question is was the work done 2 years ago that the business for the TS is closed, original owner deceased that worked on unit, but whoever did the work should have some input?
I had read into your other current post you had recently acquired camper-my mistake. I doubled checked post dates- as Im am a bit puzzled though, this and other current thread dont quite jive.
The 'brain A6060 control board controls everything- it is quite expensive. To replace more than likly you will need to drop generator. Not that difficult but some work. I assume, though your older pics looks like youve had open and more room than I have, I doubt room enough to actually remove tins for access to board.
Behind the heat sink in the rectangular box next to fan is the board. if you dont have, download manuals
