Thanks to all who replied. While staying at the Rv park in denver, nc a new Tiffin MH decided when he arrived there, the tiffin would just back up and put the trailer hitch through my front end cap and knock the fog light out and crack the bumper area all up. Well back to the shop again and while there I will have the shop fix the fridge again.
Thanks to doug rainer , I didnt get to the level you spoke of. I did disconnect thermistor while running for 4 hrs and no change to temp. That's where I stopped.
I,ll post what they find at the shop , when I find out from the shop. Thanks again to all.
