As I got home today I noticed that my stove/oven was beeping and displaying "F9" on the display screen. I proceeded to hit "cancel." It then stopped beeping and started to rattle/shake. It shook for about 30 seconds, as "Lock" was displayed on the screen. After it stopped shaking, it displayed "F9" again. Oh, and this whole time, the oven door is locked, and it still is. The stove is up against a wall, with counters on both sides, so we can't get behind it, and have no manuals, as the previous owner didn't have them. The stove is approximately 8 years old.
Any ideas? Is this a quick fix, or should I call MayTag?
Thanks very much,
