Since nobody else is posting their findings, I thought I would share what I found on mine.
Summary of problem:
My top burners all work fine, oven wont work on any setting.
Cause
2 of the 3 larger realys for the oven have failed. There is 4 total relays which supply power to the elements. They are actualy labeled on the board so you know which one is which. The one that says DBL supplies all burners with half of the voltage they need and the other relays supply the other half bringing the element to a full 240v. My DBL relay failed which is the reason why none of my elements get hot. If your main one works then its possible for your bake or broil relay to fail and you would still have one element that would work. In my case both the main DBL relay and the Bake relay failed.
Solution
Simplest solution woudl be to replace the entire PCB or if you are comfortable solidering replacemnt relays on the board that would work as well. I personaly will be replaciing the relays as they are only $5-$7 each. I will replace all of the larger 3 black ones assuming if 2 of the 3 failed than likely the other is not far behind. See the atthaced picture. The larger black ones from the left are DBL, Bake, Broil. The little black one (mine is orange) on the far left is the convection element relay.
How to Test
The easiest way to test if the relay is working would be to unplug the connector from the relay and turn the oven on. When the relay clicks and engages you should have continuity on the relay. When it is not on it should be open wih no continuity. I also went a step further and tested the control side of the relay which tested fine on all 3 so it seems the relay is the fail point.
Here is a link to the relay:

Anyway good luck with your ovens... hope this helps.
