Re: oven won't light
Tip - do not change the safety valve first even if the ignitor seem "ok" if you gently tap the safety valve and the flame comes on initially but fails to come on after awhile after each"tapping" - the ignitor is the most likely culprit
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.

Very interesting. The ignitor is working, so that means you have power and the control is working. The safety valve is working, and you have a complete circuit. So why won' t she fire off? Inside the safety valve is a bi-metal that only opens if the resistance is right. The resistance only changes when the ignitor is on. As it gets hotter it changes in resistance. This allows the gas safety valve to release the gas and ignite. Watch this:
if you removed the Ignitor the oven will not light it has a safety valve that operates at this same time the ignitor is trying to get hot once it reaches a certain amount of power it will open the valve for the gas.
you may need to replace your ignitor,and or your electronic control board.
Sound`s to me you need a new hot surface ignitor. Sorry to hear you may have changed the valve & regulator for nothing, but that happen`s quite often when you get the symptom`s you`ve described, I`ve even seen tech`s. do it. The reality is 9 times out of 10 when a hot surface ignition gas/lpg oven won`t light it is the ignitor.
Pick up part number 74007498 for approx. $40 and you`ll be cooking.
Hope that help`s. If so please take a second and rate the solution I provided here at fixya for you.
I think you are talking about the oven safety valve or thermal valve. before you change you oven safety valve, I would check the Amperage on the oven ignitor first, install AMP meter on one of the ignitor wire, it should draw above 3AMPs, if not then you have problem with the oven ignitor and not the safety valve. we hardly change the safety valve, I'll try to change the ignitor first. Have fun.
Part of the problem was my own ignorance about this particular Kenmore gas oven. It doesn't even have a pilot light. Instead, there is an electric heating element close to the burner which gets so hot that it ignites the gas. It seems that the heating element also doubles as a temperature sensor, so that it opens the gas valve only when the heating element is hot enough to ignite the gas. This heating element, called the "ignitor", no longer gets hot in my oven even though there is 120VAC applied to it when the oven knob is turned on. Therefore, the ignitor is defective. I ordered a new one on-line from "Appliance Parts of America" for $31.50 plus shipping, and this should fix the problem. If it does NOT, I'll add to this post.
