I have a Maytag Gemini Double oven gas range. I almost always only use the small top oven. Recently, when I set the top oven, it starts warming up, the bottom oven then automatically comes on, and it beeps over and over. The display says CONVECT (i didn't even know I had a convenction oven). Then it says cancel. The top will not heat. I wrote to Maytag about this and they said they had never heard of this. HELP PLEASE. We are coming up to the holidays and i use my oven a lot! THANKs:confused:
