Yes, I have!
I had a 1996 30' Excella. I was in Vermont at the WBCCI International rally. I was fortunate that I was an early worker, and one of the big wigs at the rally site ran me a drop cord into his office to save our food until Dometic got there.
Now, here's the story. First they left me a note that I needed a regulator, (the one at the gas bottles)as I wasn't at the trailer when they came. The only thing is, I have a little working knowledge of propane, and had installed a pressure gauge in line right before the fridge when I purchased the trailer, and the pressure was perfect. Still, I disassembled the regulator, cleaned it, verified there were no holes in the diaphram, the spring was good and reassembled it. No change. The Dometic people came back a second time at my request. The pressure was at 11.5 inches of water-perfect. No help from them as they said the fridge was toast. Another fellow about 3 rows over had, by chance, had purchased a new computer controller for his, and it did not fix it, so after he purchased a new fridge, offered to sell me the new one for $50!!!!!!! He had given well over $100 for it a couple of days before. Now, when I installed it, the fridge started working fine,and still was this last year when I saw the present owners of the trailer. The computer card should be suspect. Why not give Dometic a call before commiting to the other. Really, unless the regulator has oil accumulating in it, for it to 'go bad' is an unusual occurance.
Give me a land line call if you would like and I will try to explain it better; I am a hunt/peck typer and sometimes do not say what I mean to.
