You guys are edging off-track here...if she really did replace the ignitor in such a short time (with no model number) and it still is sluggish to light, the gas valve has a bad warp switch most likely. That is assuming that the correct ignitor was installed. If the amperage does not match what is on the old ignitor, this will cause the valve not to open correctly. Did anyone mention to this reader that the oven is supposed to take 45 seconds or so to light anyway? This is what happens without a model number to begin with.
Get those burner holes cleaned up so the gas can light right at the ignitor and see if this helps. I doubt you will find a replace ment gas valve for this G&S oven but with a model number we can check..
