Our gas cooktop has 1 large burner and 2 smaller ones. The larger one frequently burns with a yellow oxidising flame. This annoys the chief cook as soot accumulates on the bottom of the utensil being used. Either I didn't take enough notice in science class or I am too old to remember (probably both), but maybe someone has an easy solution for me to get a blue flame again

HI
The flame is not getting sufficient oxygen
That is not only dirty but potenrially dangerous as it will also be generating carbon monoxide.
Check that the burner airways are clear
If you cannot find the problem, get a gas fitter to have a look

The most likely cause of the yellow flame is a spiderweb some where in the mixing area which is preventing the primary air from mixing properly with the gas..
What brand of cooktop is it so I can have a look and see where the mixing takes place..
Usually a blast of compressed air around the burner and up the burner tube (if it has one) will right the problem..
As others have said Yellow Gas flames are very dangerous and can give anyone near them for any length of time a very bad headache..

I think it is Dometic. It is a fairly common config with basin on right cooktop in same SS moulding on left and both have a semi circular glass cover that folds up to the rear. I have a compressor but not sure where to apply the blast. Appreciate the advice and help. Thanks.

Just take the burner tops off and blast away with your air and while you have the tops in your hand give them a good clean as well and while you're at it you may as well do the rest of the burners..
Give it a test and report back if it is still burning yellow..

The actual gas jet might not be fitted properly, come loose. I have that problem and just made sure was tight and fitted properly. All OK after that.

I now find that the cover is screwed in place with 2 really small phillips- head screws which are seized in place. It seems this may have been a problem with one of the other burners as it has been fitted with screws with larger heads.

Well dont let that stop you just blow away at it which ever way you can and even hold your hand over the other side of the burner to force some of the blast down the mixing tube..
there is a good chance you will dislodge the problem and it will burn nice and clean again..

The stove assy sounds like it could be the SMEV type one, if same as ours you can purchase new S/Steel Burner tops (from Caravans Plus) if the original
ones are the ENAMEL type and are rusty. New S/Steel self tapping screws can be purchased from any Nut and Bolt Shop. If not using M/Home for a while
squirt some WD40 or similar on Screws leaving O/Night and with a bit of luck with the right sized small Phillips screwdriver they should undo.
Cheers Kev.

I had a look at Caravan Plus website without success so if flame gets yellow again I will give them a call. Thanks.
