Hi,

There is a possibility that the burner is partially blocked,make sure the oven is off and cool, take out the shelves, get a torch, a pin, a small piece of emery paper (or brillo pad) and a matchstick.

Inspect the burner at the back of the oven (look at the holes) remove any debris with the pin or match stick, use the emery paper/brillo to clean the igniter (this is a white stick with a piece of metal sticking out near the burner) very gently clean the metal part.

Try lighting it, if it makes no difference it's likely that your FSD (Flame Safeguard Device) is faulty and not allowing the correct amount of gas through.

It's a fiddly job looking at that so i would highly recommend a 'Gas Safe' engineer take a look at it for you.

I hope this helps.

sounds like more than switch issue probably main circuit board!!!! :) have you tried jenn aire support?

reset your breaker reprogram the clock try again what happend last time it was working self clean broiling etc

Sounds like the ignitor is weak and needs to be replaced. How old is the oven and what is the model # from the sticker on oven?
