JennAir W30400P Oven display doesn't work but oven does EXCEPT broiler

Hi
I’ve seen a few posts about the display not working but oven working - ours is like that BUT the broiler function does not work.
I suppose we can just get a new display panel (@$276) but any thoughts on broiler?
Otherwise just putting in the new panel should be fairly straightforward.
Thanks for thoughts!
