I've pulled my fridge and fixed the fan.  I cleaned out the
combustion chamber, on the theory that it was a good
idea even though the fridge ran OK on propane.  There's
more repair work to do to the van behind the fridge (both
the tank-fill and city water fittings leak), but I hope to some
day actually put the fridge back.

When I do, how can I test the propane fitting on the
combustion chamber?  I can easily enough spray some
soapy water on the top (main gas inlet) fitting, but I can't
see any way to get to the combustion chamber fitting (which
I had to remove to clean the chamber) once the fridge is
installed, and I don't know any reasonably easy way to give
it a gas supply without installing it.  What have others who have
repaired their fridges done?
