I have a whirlpool gas oven, model number SF369LEMQ0 6 years old. When I press bake on the control panel it ignites and reaches temperature. However, after turning off, it will not ignite again to maintain temperature. I hear it click, I hear the gas come on, but it will not ignite. Everything else is working fine. I read some other posts and saw that other people had the same problem, and replaced the bake burner and igniter. I was wondering if this could also be my problem. Sometimes it will ignite again, if I have the door open........ I would appreciate any help you could give me. Thanks!
