Thermador Oven Timer

Hi all,

Our home has a 1950s Thermador double oven (WO-16, I believe). The unit has two oven timers. Exactly how they work is beyond me, as we don't have any sort of manual. One of them (after getting bumped) seems to be running (you can hear a whirring sound) however thankfully the oven is not actually on.

We're wondering how to adjust it to stop the timer from moving but haven't been able to figure it out. It's been running for several days now.

Has anyone come across a manual online or anything of the sort?

Thanks,

Brian
