Oven and broiler won't come on. Cooktop burners are fine.
I've seen some notes about how the oven ignitor should be observed for the "glow" and/or tested for amperage to see if it's bad. The owner's manual suggested that the oven gas shutoff valve mey have been somehow turned off. It includes a small diagram of the valve and it points to the far right corner of the oven surface under the cooktop. Maybe I'm confused, but I see no such animal in that vicinity, even with the cooktop removed.
The manual says it's for models RGB744 and RGB745. I'd like to know the specific model number, but have no idea where it is. It's not obvious on the unit.
I'd like to at least get the baker working.
Advice? Thank you,

It's troublesome, thought, that the broiler won't fire either. Is that not another ignitor/burner? I can't imagine both ignitors failing at the same time. All the cooktop burners are fine.
What I really need is a diagram or something that would show me how to get to and expose a given part.
Re: Oven and broiler won't come on. Cooktop burners are...
Have you run the self-cleaning feature recently? I had a similar problem on my stove of the same model, and it was the switch that detects whether the oven latch is engaged (if it gets stuck and thinks the latch is locked, it will not ignite the main burner or broiler). An easy way to check if that's the problem: without touching the latch, turn the controls to Clean. If the burner lights, that is your trouble.

Most modern gas ovens have a device called a Glow Ignitor to light the burner. If this ignitor has filed, it will NOT left the gas valve open-- (Good thing, right? :-) )
You say the broiler lights fine-- so let's observe something when the Broiler lights: Do you see a bright glow near the Broiler burner? (Usually toward the top rear of the oven--)
Well, you should see a similar bright glowing near the BOTTOM rear of your oven, for the main burner to light off-- If you do NOT see this glowing-- then you need a new ignitor-
You can remove the bottom burner cover, and dig deeper into the repair if you like- But a new ignitor needs to be exactly like the failed one-- the safety circuit is very fussy about the exact same ignitor-- or it will not allow lighting-- even with a new 'generic' installed.
How deep do you want to go into this repair?-- Maybe it is time to call the service people into do the job?-- You can tell them that you think the ignitor needs replacing-- and approx. what will they charge you for the service call and the ignitor?
Here is an observation you can make thru the oven door:
When you turn the oven on to BROIL-- do you see the bright glow of the ignitor? (It is almost like a light bulb was in there-- buy the burner!)
When you start the oven (on BAKE) setting-- do you see a similar bright glowing light? (Tho down lower, near the Lower Over Burner) If you see the bright light-- then the ignitor is apparently heating up-- If not-- then, YES-- you are likely right-- Ignitors are fairly common failure items-- and they can obviously stop the burner from lighting-
Possibly the ignitor for the main oven burner has failed--
An observation question:
When the Broiler 'lights' and comes on, do you notice the ignitor glowing bright, before the gas valve (to the Broiler) opens, and you get the Broiler lighting---
Now-- for the main burner to come on, -- there has to be a similar bright glow from the MAIN BURNER ignitor, before its main burner gas valve can open-- No Ignitor?-- No ignition, and not Main Oven burner!
If the broiler burner is not coming on it may be a bad ignitor or the ignitor may not be getting power. Observe the ignitor when you turn in on ans see if it glows at all. If not then test for power to the ignitor if you have power and not glowing or lighting replace the ignitor. If it glows but does not light the ignitor may just be weak replace it.
if your oven has a hot surface ignitor it will be visible when looking in the broiler section of your oven if you have an upper and lower burner the bottom of oven will have to be removed to find the ignitor when oven is turned on ignitor should glow a bright red the ignitor works off 120volts if you have the knowledge and testor however a visual inspection if ignitor does not glow and part of the igniter appears white with a smaal crack line in the middle it is probbably broken at that point also if you have testor you will have a continuity reading threw the ignitor
Hi, it sounds like the oven ignitor might be bad. Remove the floor panel inside the oven and you will see the ignitor attached to the burner assembly. Turn the oven on and see if it glows. You can test the connection for the ignitor and see if it gets 120V to it. The most common problem with the gas oven is the ignitor. Most of the time, the ignitor glows but is not strong enough to open the gas valve.
Please let me know if this was helpfull or if I can assist you further.
Turn on oven. Ignitor should begin to glow. (if no glow after 30 seconds or so, check to make sure you have 120 volts to ignitor) Observe amperage draw using a clamp on amp meter. When amperage reaches 3.2 to 3.6 (for square syle ignitors) the oven safety valve should open, releasing gas and lighting the burner when the gas hits the red hot ignitor. For broiler, just substitute the word broiler for oven. Old ignitors get " weak " and may not draw enough amperage to allow safety valve to open. Also, voltage will affect the amperage draw, as lower voltage = lower amp draw.
