Wanted-working fridge for a '89 westy.  I'm throwing in the towel on mine.
The problem for those who missed my earlier postings lies with the propane
burner side.  It works fairly well on 110 AC and not quite as well on 12 DC
but very poorly on gas.  The flame is yellow, it's hard to light and
eventually (after a few days) the cooling pretty much stops although it's
still lit. Here's what I've tried:
 First I educated myself about this peculiar bit of technology to the best
of my ability.  Thanks to the list I now have a pretty good working
knowledge of the Dometic 3-way.  I also have the experience of having owned
2 other late model Westies so I'm not deluded about what to expect
cooling-wise.  I've replaced the burner orifice and the regulator on the
tank.  I've cleaned everything deemed worth cleaning.  I've taken the damned
thing in and out more times than I care to remember.  I've turned the whole
unit upside-down for a few days before reinstalling it.  I even rigged up an
extention gas line so I could light the thing without having it installed so
I could better observe the workings of the cooling unit while it's working.
Anyway, I give up.  But I'm still willing to listen if anyone has advice on
something I may have missed.  Or if you know where I could get a good used
one let me know.
