Hello there Gary and welcome to FIXYA

Usually when an oven won't bake properly or stops baking , it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself. The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame. I would disconnect the power to the oven then unplug the wiring assy and remove the part then clean all of the terminals really good then reassemble it then try the oven again if it still does not work properly i would go ahead and replace that part ok
Please keep me posted on how this is going i can give you more help but this is the most common problem ok?
Best regards Mike

That sound to me like yall have some carbon buildup on the igniter. On this stove the igniter does 2 jobs. It lights the burner and verifies back to the control that Houston we has ignition. If junk is built up on that ignitor then she won't be sending verification of ignition back to the control. That white residue needs to be removed. NOTE: I don't have your model number I am going by what you describe that this stove is a Direct spark ignition model. If you have a normal ignitor it probably is weak and not drawing 3.5 amps to open the valve. Post a model number (bottom drawer frame)

It seems to me that espically if brand new and this happened th efirst time you used it,the gas pressure regulator was set for propane at the factory instead of natural gas

as far as for the leak that valve needs to be replaced in warranty but the decreasing flame size is due to incorrect regulator setting

You may not have purged out all of the air from the gas line, it does take forever...

Please do not use the stove, get it checked out for a gas leak it is very dangerous.

my oven won't work when I turn it to 450 it only goes to 100 and won't heat. Can you give me a solution to fix it
Thank you
