Hey hun.. yeh i looked at it and i think it is different to yours.
But now from memory in my old rental place we had an oven that you had to start the timer in order for it to work. And when the timer turned off, the oven would turn off. PITA thats for sure, i think it was a safety thing. But maybe if you can, give that a try. Set the timer on the clock and see if the oven will turn on.
