Hello out there! If anyone has an idea on what might be wrong with my oven, please respond! I have a gas stove and oven, with an electric starter for the oven. It is a GE Hotpoint oven, only about 4 years old. The problem----it turns itself on for less than a minute, then turns itself off...This has been happening a few times per day. What could be up? Thought I'd ask around before calling an appliance repair person. Thank you for any insights!!!!
