Oven doesn't work, but stove does, different from others

Well the other day my wife says that the oven does not work. I turned it on and nothing. I know before that I would see the ignighter glow through the vents on the sides of the stove, then I would hear the gas turn on and I could hear the whoosh as the gas lit. Now you turn the knob and nothing happens.

Here is what I checked so far:

I checked the valve at the back and seemed to have 120VAC at the terminals of the safety valve. I disconnected the igniter and checked it’s resistance and it showed 15.5 MegaOhms, it does not change when I tap it. I am not sure what it should read.

The igniter is this one:

Safety valve:

The Safety valve seemed to not be working. Looking at the schematic and wiring. The igniter is wired in series with the safety valve. I am guessing now that the resistance of the igniter keeps the current low enough that it keeps the voltage low enough to not damage the valve.

I did not check the resistance on the terminals of the valve, and I am pretty sure I burned it out. I removed the igniter connector and jumped the connector out. I turned on the oven and lit it with a BBQ lighter. it came on and the burner lit but went out after about 5 seconds. In hindsight this looks like I made about a hundred dollar mistake. I checked the resistance and it’s open.

My questions are:

I am guessing the igniter was bad, but what do the experts think?

What should the resistance of the igniter be?

Is there another (cheaper) valve that can be substituted? (if I did take it out)

If the igniter and the Valve were good to begin with what else could have caused the stove not to work?

Thanks for any help.

Could really use some help on this. Speaking with the Appliance repair store they were unable to tell me what the resistance of the igniter is they say if they suspect that it is bad they replace it. To me this is not trouble shooting it’s parts replacing and that is a not what I am about.

I have taken the oven apart and there are no other componets that would drop the voltage to keep from damaging the safety valve so the igniter must be the only thing. I really need to know what the value should be so I can I can tell if it is out of range and order the parts. I would like to order the parts and get it fixed by this weekend.

Thanks
