Last year the lower oven would not heat up. Traced the problem to the igniter so I replaced the lower oven igniter and it worked until about a week ago. I also repaired the deflector panel on the underside of the oven bottom to prevent it shorting out and breaking the igniter. A week ago I replaced the igniter with the correct part, also checked the heat deflector which was fine but the igniter did not go on and oven still did not heat up.
I called a technician and explained the problem who said it needs other components and estimated it would cost $450-500. + tax to fix.
Anyone have a similar problem with a range like this and have any idea if it does need "other components" and what those components might be? I would like to fix it myself if possible.

Your reply with information would be very appreciated.

Why would that be necessary?

the igniter did not go on

Normally there are 3 possibilities for the ignitor not glowing; a defective ignitor (# WB13K10043), an electrically open gas valve (# WB21K10161) or the control not powering the ignition circuit.

The gas valve should be able to be tested for continuity to see if it is bad. If neither the ignitor or valve is the problem, the electronic control (# WS01F04307 replaces # WB27M1165) is likely responsible and needs to be replaced. Unfortunately if the control is required, it appears to be discontinued and may be hard to find.

Thank you for your reply. Since the upper oven is getting gas and works fine it appears to point to #3 the electronic control unless there is a separate gas valve for both the lower and upper ovens. Are there separate valves for each? If it ends up being the electronic control is this a DIY replaceable part?
Again thank you for the advice.

The upper oven working or not has nothing to do with any of the components I mentioned. It doesn't relate to the other oven's operation at all.

Yes. That's how they can be controlled individually.

By elimination I have ruled out the ignitor. There appears to be no power coming to the ignitor when I turn the oven on. Would that mean the problem is likely the control?

That is ONE of the TWO possibilities remaining as I originally stated. Did anyone do a continuity test on the gas valve?
