High orange flame on trailer propane stove?

[jeremyers1]

I was camping with the family this week, and while we were out, one of the burners on the propane stove in the kitchen went from a nice blue flame to a high orange flame as in the picture.

Any ideas what caused this and how to fix it?

An orange flame indicates a lack of oxygen at the burner, but one of the possible causes of that is actually excessive LP gas pressure.  High pressure forces extra LP through the burner and its air inlet is insufficient to make a blue flame.  So, either too much gas or too little air.  A failed LP regulator can make the pressure too high, or some dirt or grease around the burner area could be blocking air.

Since you said one burner, the regulator is probably OK and you have debris in the air intake.

Do the other burners do the same thing?
If they don't, I would also suspect something spilled in the burner. Taker it apart and clean it.
