I have a Kitchenaid stove (model KGRS202BSS0) that does not always relight while baking. Ignitor was replaced 11 months after purchase. Now 2 months later the oven is starting to do the same thing. While baking the ignitor will cycle 4 times but the oven does not light. After 2-3 cycles the oven lights but I am concerned about this becoming worse and the company not backing it up because it is out of warranty. Any ideas as to what the problem may be?
