Hi, this is probably not super off-topic since what I'm looking at is
likely very similar to what's inside our familiar RM182, so please bear
with me.

I just picked up a used Dometic RC2000 mobile refrigerator. It's about
the size of a small ice chest. It is a three-way unit, just like the
RM182. On electricity it works fine. It probably works fine on propane,
too, but there seems to be an issue.

The piezo clicker is pretty darn tough to click so I opened the little
spy hole on the back and used a butane fireplace lighter to light the
burner. The burner lights, a nice little pilot lamp.

But a small flame popped up outside the burner box. It's coming out of
the vents in the air mixing tube. One end of the tube receives the
propane line. The orifice has got to be around there, too.

I'm guessing that the propane blows through this tube toward the burner
and sucks in air through the vents, creating the proper mixture to burn
on the burner. But it's pretty worrisome that a stray draft of air
causes a flame to pop up out there.
