Wanted to add a note to this refrigerator thread...
We went camping last weekend to Shades State Park. It's rustic. Went to light the refrigerator and the flame was kind of small, but it lit.
Before I could get the cover back on, two little flames started streaming out of the sides of the burner! These two holes would normally draw air in to mix with the propane on its way to the burner. But in this case there were two flames about an inch and half tall and yellow. They were quickly melting wires and creating smoke.
I shut down the gas and of course I had to try it a couple more times just to make sure. Each time, the flame in the burner would jump down to those holes, light up and start to burn up the camper.
So we finished our trip using the generator to cool off the fridge for an hour or so a day, it was quite cold at night anyway.
Once we got home, I took the burner assembly apart and put on a 10x Jeweler's Loupe to look inside. I shone a light in the burner end and put my loupe right up to the end where the gas line attaches. There was a spider in there, and with the magnification of the loupe, it looked like it weighed a pound or so!
I blew him out with compressed air into a pile of snow, put everything back together and it works great again.
I really think that spider might have burned up our trailer if I hadn't noticed that funny yellow glow. I had almost put the cover back on!!
