propane stove problem

If the burner works correctly at first then one can assume some propane is leaking out of the air port instead of going up to the burner. When the propane leak is sufficient, it catches fire. So, you may have too much propane coming out of the orifice (jet), too much air mixing (very likely), or a leak (also likely). So, check for a loose fitting or broken fitting allowing propane to leak out slowly. If you don't find a leak, then reduce the amount of air that mixes with the propane. That should discourage any leakage from the mixing point since that leakage is what is igniting. Good luck.

Not sure if this would help you. I had a some what simular problem. Mine was a melted plactic bushing melted where the burner tube meets the valve.
I ordered a couple and replaced it havn't had anymore problems yet.

I'm going to suggest the air vents are too large, or the igniter is too close to the orifice and not the burner. Look at the other burners that are working correctly and change the front burner accordingly.

Thanks for the input. More info...The problem doesn't occur until the burner has been turned on awhile. So as the burner is working correctly, with the fire on, all of sudden, the fire comes out of the tube's air port. So I am not sure the igniter even comes into play, problem wise.

This is a new stove under warranty, and was looked at once already under warranty. They made the problem better, but not fixed 100% yet. It is going back for a second look this week (other items too), but sometimes, stuff like this is just easier to fix yourself.
