Bosch HBL3350UC wall oven heating to 500+ regardless of setpoint

Hello all-

We bought our house in October and noticed the oven cooked very fast and burned almost everything. We started adjusting temps and times from recipes to accommodate. Recently I put a thermometer in the oven just to see how off it was, and realized the problem. Whether the oven is set at 225 or 350 it heats to 500+ degrees. I ordered a temp probe replacement but that hasn’t fixed the problem.

After disassembling the interface portion of the oven, there are 2 boards Inside that I can see. A larger green control board and a smaller black board. Which should I order and try to replace?

Thanks!

Brian
