Ok people. I got home and took the rv to an rv service center as I was unable to resolve the problems on my own. The rv service center charged me $112.00, had the RV for 5 days and told me it was fixed and everything worked. HOWEVER when I went to pick it up, he had just simply flipped the breakers on the generator (duh! I didnt know about those) and replaced the transfer switch fuse in the engine compartment (yay!). While showing me all the appliances worked, the refer started to work but quickly died under all power conditions with no lights anywhere (an RM2852 Dometic Americana), plus the furnace would not turn on, and there are 2 lights not working. Everything else we tried, including the air conditioners, seemed to work. He told me I would have to make another appointment and bring it back for more troubleshooting which would take days. But he did confirm there was 12 volt to the refer and fuse in power converter was good. He suggested in the mean time I use a cooler and space heater, ugh. He said the furnace and refer were on the same circuit though. TODAY I went out to the RV and started the generator, I just happened to have the power converter fuse box open and noticed a spark fly when I started the generator...... so between that and the boiling battery I experienced before, I am wondering if it could be the power converter? Though the RM2852 had some things recalled and there is more troubleshooting to do on it according to my research..........
