My double oven replaced a 22 year old double oven. When we first I stalled it and started it up we would get a code and the oven would turn off. This was very disappointing and I was bracing myself for a long wait to get it sorted out. But when I called on Monday morning, they assigned a service call that afternoon. The technician arrived and quickly figured out the problem. (A loose wire during shipping). Since then both ovens have worked flawlessly. They heat quickly and cook evenly.
