Hello, i have a brand new Kitchenaid kgrs807sss gas range and am already having troubles with the oven. The flame does not light on the bake burner consistently. It always lights right off when the oven is cold but once it gets up to about 325 it wont light always. I can hear the gas valve open and hear the gas flowing and the igniter snapping about 4 times and then valve shuts off and igniter stops to try again in about one minute. Usually it lights after a couple tries but not always and you can smell gas in the oven. One time after about three tries it shut off and must be turned off and restarted again. I had a service tech here today and he adjusted the airflow to the flame at the back and it worked while he was here and now already it is not working again. I have read up about the 8 holes in the lighting area of the tube and yes it has 8 holes.
Thanks in advance for any help.

Thanks Simon for the super fast and helpful reply! I will try that and post the results. FYI I just tried to run the selfclean mode twice and both times it shut off because at the hot temperature it tried the three times to start up again after reaching its temp and then locked out and had to be restarted from cool. So it obviously has something to do with when it gets hot. Any idea why this is? I am a mechanic myself and am trying to understand why this is happening. I've done tons of camping and barbequeing and have never seen anythin like this before. I was sure the service tech would know right away what was wrong but he also seemed to be shooting from the hip.

Hi.
It has to do with not enough gas flow when it's gets hot.

Well that didnt help...

Hi.

Thank you for the helpful input. It's good to know about the altitude adjustment.

Thank you again.
