GE Double Oven - Bake and Broil - Multiple Problems
There are two problems. The first problem is that we can only use the upper oven about once per day. Once the over is on, the temperature can not be changed. If the oven is turned off, the oven can not be turned on again for many hours.
The lower oven essentially doesn't work at all. The control panel indicates that the oven is on, but it does not get warm at all. Bake, broil and clean do not work for the lower oven.
