Trying to help a friend with her oven. Top oven, which can is both conventional and convection. Turned on convection heating and heard loud pop. Opened oven to see a little smoke and a burned hole in in the convection fan cover.

As a result, none of the upper oven heating elements (convection, conventional or broil) would work. Also, the fan for the convection system wouldn't work. I removed the convection element/fan cover and noted part of the element had basically disintegrated...

I replaced the convection heating element hoping that would solve all but realizing if it didn't there would be nothing lost as it would need replacing regardless. Now, the convection fan works but still none of the heating elements. Could someone please steer me in the right direction? I have looked online and it seems the next step is the wall oven control board (part number WB27T10569). If, in fact this is my next step, where is it located and how is it accessed? Is there a way to test before replacing? For your information, the lower oven is still working fine and the display board is still working, as well.

Thank you so much for any and all assistance.
