Fridge running on propane

[Home handyman]

The fridge in my coleman popup is "popping" when the burner is lit. When it pops, the flame shoots any open space around the burner.
Has anyone else been through this? Any ideas how to resolve this?

Have you checked the air intake to the burner for any obstruction (i.e. spider webs)? These can restrict air to the burner and cause "poping" when igniting and a yellow flame (the flame should be blue) when lit.

Thanks. I'll check that. Flame is yellow.

With a yellow flame you have a air supply problem. Check the burner tube for obstructions, and clean orifice, or for a couple dollars jst replace it.

Home handyman....You need to clean the burner (usually will have some rust on it and can be brushed with a small wire brush and then blown out with air) and then wipe the gas orrifice at the other end of the burner tube with some alcohol. After you've done this, you'll find an adjustable collar on that burner tube that regulates the amount of air to be mixed with the gas. The collar has a set screw you can loosen and adjust. If the burner is not burning a combination of orange and blue with a steady flame, adjust the collar one way or the other. There should be no yellow in the flame.

The burner tube itself will often get a small spider in them and they build a web across the interior of the tube blocking flow. If you have issues with spiders, buy a dog flea collar at the store and cut it into two or three sections. Screw or wedge the sections into the back of the refer. This will keep spiders away for quite awhile.

Spider Webs.....yes indeed.
