Propane leak in Dometic 660 refer
My '68 Safari's Dometic refer fills the cabin with gas odor when it's on propane. The leak must be after the rotating valve that you access through the side panel to turn on the gas, since the smell goes away when I close that valve and use AC to run the refer (which doesn't do much of anything in the current 102 F Texas heat). I can't find the leak with bubbly soap. There is no yellow in the flame--it runs loud and blue. Where could the leak be, and how can I fix it?
