Default Oven broiler stuck on!!!!

Was getting ready to cook dinner and turned the oven on and the display said clean except the door didn't lock and only the broiler element came on. Nothing would turn it off so I hit the breaker. After a few minutes turned it back on and the same so I waited a few hours to try again. This time all looked normal so I hit the bake button and looked normal so shut it off. Well again the broiler came on but the display showed the oven was turned off.

Oven is a 2000ish whirlpool super capacity 465 mod: GR399LXGQ2

Tested temp sensor and it was 1100 so should be good.
Tested for a short in the broiler element and it was good.

I do see some dry joints on the control board which I assume is why the lock didn't work. They are on wires that do all run over to the limit switch and drive deal for the door lock.

The broil contact looks rough but was open.

I'm not sure how any of this would kick the broiler on element on. Any tips?

Nichicon PR(M) 1000uf 50v brown
Nichicon KL(k) 10uf 16v orange
Surge ??? 4.7uf 50v blue
