Whirlpool Double Oven GBD307
The upper oven (which is also an electric convection oven) is heating on its own without being turned on. After trying to turn it off in the usual manner, it will stop for a short period of time. However, it will start up again on its own. The only way to stop it is to turn off the circuit breaker. The oven was purchased new about four years ago.
