Oven turns on by itself

I bought a used oven after my other one failed and back to where I started. The oven just simply turns on by itself. Any ideas on how I would approach this problem and what it might be?

The model number you posted does not come up. Verify and repost it, please.

Most likely the problem is a stuck closed relay on the control board (aka a clock).

  • The part number for the control board is AP3492305
