My oven door is stuck

I have called an emergency repairman and he thought he could come, but I am thinking maybe he can’t. I have worked most of the day trying to get my oven door to open. I have thrown the circuit breaker and put my hand down into the den of electrical death, looking to manually spring the latch. (I took a picture of the electrode placement of those I had to unhook in able to get my hand in there.) I have used high tech coat hangers and ALL SORTS OF THINGS AND IT WON’T OPEN AND I AM GOING TO PANIC AND I CAN’T EVEN PUT MY HEAD IN THE OVEN . . . but then it’s not gas anyway.

Now I could start removing screws but I really, really think that is not wise. I mean I already had to take out two to expose the lock mechanism.

Maybe I will sit down and try holding my breath and . . . I think the reviews on this technique are good, however.
