Our GE jgpb33seh5ss oven stopped working. I figured out it was the ignitor and replaced it. This fixed the problem we were having where the ignitor was not turning on (glowing) and starting the stove. After being repaired for about 2 months, we started having a problem where once you turned the oven on, the ignitor would glow and after a short time, start allowing the gas to flow. The problem was that too much gas was coming out too soon and once it "ignited" it would blow the door open a couple of inches. I had hoped I just had another bad ignitor (this one with a different issue) and replaced it once again. Unfortunatly, it still does it. Even after it comes on, it is not getting hot enough even though the oven is not trying to light. For example, tonight we tried to bake cookies. They have been in there for over 1.5 hours and still are not ready at 350. Is this maybe a bad thermostat? Thanks
