[C320-list] Oven not starting??

[Scott Westwood]

We have, what looks like, the original oven (Seaward?  Not at the boat right now).
The stove top starts like any normal gas burner with heat sensor that has to get hot enough for it to stay on.
When I try to start the oven I hear no gas hissing no matter how I turn/push the knob.  Held a hand held grill starter (long cigarette lighter kind) next to the oven's burner but it never caught or even flickered.
Next time I get to the boat I will try to heat up the oven's sensor (with knob turned half way on)  to see if that will open the flow?  Didn't think of that last time I tried to start it.
Familiar issue?  Thoughts?  Sounds like the knob/switch might be bad? 
Thanks,
