I’m giving up on selling this thing, and will bring it with me to DMS when I’m there from 1-4pm tomorrow. If you’re keen to take and repair it, it is yours for free.

If I were in need of an oven, I’d buy a cheap $20 temp controller and relay. Then you’d wire that up to control the top oven temperature and use the knobs to do the bottom one. Might look a little odd with a DIN-mount temp controller sticking out, but it’d get the job done.
If no takers, it is going to the appliance recycler.
