We just got a Bosch oven whose timer would count down to 1:01 and stop. Further, it has two timers and only one of them did this, elevating this bug from surprising to nearly inconceivable. Then, to fix it they had to send a repair person out with an entire new controller board.

So yeah, some fundamental restructuring would be good here. (BTW, to be fair, the controller was made by Diehl Controls, not Bosch.)
