My Dometic refrigerator generally has cooled decently, getting the interior
down to 40-60, depending on the heat of the day.

However, it wasn't staying lit, so I pulled it and cleaned the burner box
and so forth.

Now it's staying lit, but not cooling.  It's 73 degrees inside, which is at
most 20 degrees cooler than the outside temperature.

While I had it out, I turned it on it's side.  Could that have screwed up
the coolant?  If so, is there anyway to restore it?

Thanks for any help
