Hey all-

I have a gas range that the bake and broil do not work. No spark, no gas noise.

The cook top works great.

So when you set it to bake at 350 nothing happens? No sounds at all?

I need to ask BB for the tech data sheet.

Hey Jake-

Nope, no noises other than relay click when I press back or broil. The only error I get on the diagnostics mode is that it indicates the touch panel is defective. But when I cleared the error, it didn’t come back...The relay clicks. That’s it. No gas, no spark...

I did find a forum out there indicating the harness wiring could be faulty yet not look defective...

And the spark board has a couple burn spots near a couple of the resistors...

thanks
Paul

Thanks Paul,

Are you referring to your clock oven control board with the burn spots?

If so, then you will need to order and replace it.

Here it is for your model:

I don't see a DSI spark board on this model, I see a spark module.

w10511278 revision b - board has two 47R 5% grey resistors that appear to have gotten hot. If someone can tell me what those are I can order and solder new ones on.

Thanks BB, my bad I do see the DSI board now.:)

As techs we don't repair at board level, we replace the board.

Here's the DSI board for your model:


I'd first check your wires down at the bottom drawer, another member said this:
Ended up being some pinched wires behind the bottom drawer. Wires are extremely thin, very poor design/placement of wires.

I’m an IT guy and can read a multi meter, solder, etc. so if anyone knows if those resistors are all I need; I’ll give it a try.. I appreciate help thus far!

That's the problem, no one will know because the schematics are not available to the general public at board level, because they don't want you to replace components on the board.:)
