Why are ovens so hard to turn on?

Update: No I mean electric ovens.
Update 2: You have to do it a certain way or they don't work at all and it's so annoying.
Update 3: You have to do that stupid thing where you twist the timer for no reason or they don't turn on!
Update 4: I'm not in the USA that's why and it's a Chinese electric oven which seems to be the norm for less expensive over in the Southern Hemisphere.
