If this is your range, and you have a digital panel on it, likely there is a short in it that will go on and off at random, annoying intervals. I have a GE Profile, 10 years old, and have been going through this for months now. It's not unsafe--just annoying. Fixing it is half the cost of a new appliance so not doing that. Just going to live with it until I decide what I want to replace it with.
