Also, the top sealed GAS burners puzzle me....
There is one large opening, about 1/4" inches in diameter in the
circumference of each burner. The hole is to the rear, many times
larger than the standard burner holes and is not near the spark
igniters. The problem is that a large volume of gas jets out of each
of these large burner holes, sending a small finger of flame up the
side of a pan, sooting up the pan.

What was the purpose of these larger holes?


All gas burners have a large opening to admit air which mix air with the gas
before combustion. They generally have a sleeve in the vicinity that can
adjust the size of the hole. Move the sleeve until the flame is the standard
blue.

Without Oxygen, you'll get a yellow flame signifying incomplete combustion
and that will, as you found out, generate soot.

Anyway, your problems about "F1" and this weird flame are not connected.



Thanks for the above but your comments about an opening to admit
oxygen is not applicable.

I'm not talking about that.

What I'm trying to describe is a "sealed" gas burner - typical on the
top burners of newer gas ranges.

Around the circumference of the burner is a series of small holes
allowing gas to jet out - so far - pretty typical.

However these burners have one large hole, about 1/4" in diameter on
the circumference that lets a large volume of gas jet out. In a sense
a large "finger" of a gas flame that rises up the side of any pan that
might be on the burner. These lharger holes or jets or not near the
spark ignitor for each burner - so ignition has nothing to do with
their purpose.

I know that "F1" computer issue and the flame is not connected....
I didn't imply that it was, did I???
