Our unit is a Dometic 15k btu . Our TT is a 2014 Freedom Express 261SE BH. The tech opened up the cover inside and said "yep". When I looked last night, all I saw was a lot of wires and a very small label. I did not want to touch anything. While we are on the road, all the switches on the electrics are off. When we got home and started to unload, we found that all of them were on. I guess from the technician at the dealership. Would that hurt the converter? It was only connected to the truck.
