Refrigerator Replacement? - Event Date: 01 May 2017

I have a 2011 181G and the Dometic 8501 refer won't run on gas.  It comes on for a few seconds then goes out.  I've had it looked at by a couple of "technicians" but so far nobody can make it work.  The next option is to shell out $550 for a new electrical box which may or may not solve the problem.  At this point I think I would be best served with a new refer instead.  Domestic doesn't seem to make that particular model any more and I can't find the same size anywhere.  Has anyone replaced their refrigerator with another brand and/or model?

Do like CharlieM said, but also clean the orifice and the thermocouple. ? did you by any chance get an exchange bottle of propane? 

The techie that came out said I had a bad LP regulator valve that was providing too low of pressure and that's why the flame started then went out.  $200 later and a new valve and the exact same problem remains.  I do have a new regulator valve tho.

I had the same problem after I used an exchange tank, plugged the orifice, cleaned orifice everything was fine. I also had the problem with my house furnace Talked to a furnace tech friend, he replied I shouldn't tell you this clean the orifice. And all was well.

I have the same problem, 3 1/2 weeks and a lot of money at a factory certified repair tec.  Replaced almost every thing, I told they I was not paying them to jus replace parts, their recommendation junk it and replace it.parts are very hard to get. Right now I just cap off the gas line in the rear compartment we mostly stay in full hook up. I Calle several rv repair shops and no one,I mean no one had anything good to say about that model
