What component on there would be burnt out? I could probably replace it myself.

Probably the bake relay.
I do not know where it is on the board but you just have to trace the bake output E7 on the board back to the relay.
If it is just that the relays contact are shot then replacing it will fix the problem. This also applies if the relay's coil is open.
If it is that the electronics that control the relay are bad then this would be difficult to fix as a schematic of the board is not available.
You can confirm that the relay is not closing by measuring from E9 to E7 on the board.
If you go to bake and there is still 240 volts across these test points then the relay is not closing.

Again be very very careful if you do this 240 volts is lethal!!![/COLOR] |

Well, when you hit bake you can hear a click from inside there but it only stays on for a few seconds. I tested both bake element leads individually to ground, the one that comes out of the little relay on the bottom gets about 115v but the one comming from the control panel does not register anything.

So E9 has 120 volts on it all the time and E7 never has voltage, correct?
I am not sure what is going on here.
Using ground as a reference point can be confusing when working on the element circuit because it does not use ground. |

You'll have to forgive my ignorance, my wiring diagram reading skills are a bit lacking. E7 is the left hand wire for the bake element and it also has the left hand wire for the conv element spliced into it. When bake is off it reads ~2v and goes up to ~.05v when bake is on. E9 goes down to that little relay or whatever it is near the bottom of the back of the stove, there are several wires that come out of it one of which is the right hand wire for the bake element. This wire reads ~3v with bake off and ~115v with the bake on. Attached is a photo of the back of the control board. Dav0 attached the following image(s):

If you are using Neutral as the reference then this line should have 120 volts on it.
Ci9rcuit path is W7 , bake element , NC to C of the Relay 240V , DLB Relay Contacts which shoul be closed to L2

This wire should always have 115 volts on it as iy is hard wired to L1.
It is directly connected by the R-4 wire. |
