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.:)

Hey all - I just thought I would post an update to this in case it ends up helping someone else. After many hours of messing around with this thing and researching forums such as this. I did give it a break and just didn’t bake anything for awhile LOL.

However I finally conjured up the want to mess with it again. And fixed it! again, I am no appliance repair person however I am very analytical and can pretty much fix anything. As with anyone reading this it took a while because I have a lot of projects going on at one given time LOL, you probably do too

Anyway I probably should’ve just follow the direction of the unit which indicated it had a stuck button. I was a non-believer as I tested them all and never seem to have an issue. They are pressed beeped didn’t press twice. Etc. Anyway this thing scared the shit out of me a couple of times in the middle of the night because it became possessed depending on the temperature, humidity and guessing barometric pressure. That is when it would start pushing buttons by itself LOL. And that’s fine if that ghost wants to bake. But at least make me some brownies or something LOL

Anyway, since I had no idea which buttons were stuck because they all seemed just fine, I decided to swap a couple of the heavy use buttons with the never use buttons. I.e., start cancel, clock, aqua lift, bake, broil, you get the point. Sure enough, that fixed the problem at least for now. I probably should figure out what part number those buttons are and just order new ones. If you know how to solder on a circuitboard. It’s easy money. However I would have just put the entire button panel into an ultrasonic cleaner but guess what you cannot find isopropyl alcohol right now. Because of all the assholes hoarding stuff they don’t need, That probably would’ve fix the problem all by itself. Anyway I hope you guys stay healthy. Have a nice day
