Hi Everyone,

I recently purchased a Kenmore Gas Range Model 91136665790 or variant

https://usermanual.wiki/Kenmore/91136665790.978328865/view

The broiler igniter will not glow. I am trying to determine if it is the igniter or the electronic control board. I think I know how to test the igniter, and I can get to some of the wiring under the stove. I am trying to avoid pulling the stove out, because it is heavy. Also, I have it way up on the adjustable feet and don't want to risk bending them.

I see wiring coming into a junction box and leaving the box underneath the oven (I've attached pics). I'm trying to figure out where to test either the igniter or the board, to see which may be at fault. 

Pics Below.  Hoping someone might offer some guidance.

Thanks!

You can actually access the ignitors from inside the oven.. You should not have to pull the stove out or anything like that. Then you can use a ohm-meter and just check the ignitor to see if it has continuity or you might physically see if it has burnt out

Thanks... I realized I can access the igniter from inside the stove, but I'm not sure how to get to the igniter leads to test it. Is it likely the leads run from the igniter all of the way back to the "junction box"  in the pics I provided? In other words, should I open that up?

Yes, I see the ignitor wires in one of your pictures.. they are the thicker material coated wires... the broil ignitor should have a connector at some point that you can unplug and test with a meter from there

I found the wiring diagram!  Looks like the purple wires are for the broiler igniter. One comes off of the Broiler Control valve and the other comes out of the multi-pin plug in the far lower right-hand portion of the diagram.

Do the "C"s inside of a circle near the igniter mean there is a connection there (wire nut, maybe?)
Thanks!

I pulled the igniter. I had hoped I might pull the connections that attach it to the main harness through, so I can check resistance, but no...   Looks like I will have to access the back of the unit for that.  

I do have access to the box underneath, that includes what I think is the gas safety valve. (See pics below)

I should be able to check for voltage to the igniter here, shouldn't I?

Yes the metal box is the gas valve.. also that picture of the ignitor from what I can tell I think I do see a burn mark which is likely why it is not working.

Hello All!

I as able to get the igniter out and detach it from the main harness. Igniter is open circuit (OL) and there was 120 V at the main wires, when the broiler was switched on. 

I've ordered the new igniter.

Much appreciation for all of the help!!

It looks like the bake and broil are the same for this model which is not usually the case but this is the one I show for your model https://www.appliancezone.com/wb13t10001-ge-oven-igniter/
