Where is the o*****e located in oven range?

Question

I posted so many questions about this and i'm not getting the answer i need.I converted a propane stove to natural gas.I called around and they said it was self adjusting.I have the burners working but the oven is not heating up properly.It take awhile to heat to 350 so i need to adjust the o*****e in the oven but my boyfriend can't seem to find it.Where is it located?I'm frustrated and probably should call a tech to come out and do this.So any info on where this is located or how to find it and do it would be much appreciated.

See the little rectangle just above the left hinge?  I think that could be called an o*****e.
