Trying to trouble shoot my oven problem. The top oven comes on and starts to heat up but will not come all the way up to the set temp. It just stops heating and sits there cooling down. No error codes or sounds, just stops. Reset it for a higher temp and it comes back on and starts to heat again, then stalls out. The bottom oven works as normal.

I thought it could be the temp probe so I switched top and bottom probes, no change. Bottom still works good, top still stalls. I now assume it is the control panel but am realizing there are 2 different control panel parts in there. W10312205 and W10119142. If they were cheap I would take a chance, but for the cost of them I would like to hit the right one. I can't find any way to diagnose, so I thought I would check in here for thoughts. Being as the bottom works would it indicate that one of these boards has to be good and point at the other one?

Any advice appreciated.
