Report "I have a double dietrich oven with an analog programmer for both ovens. The small top oven is working fine. When I try to put on the larger bottom oven using the dial it seems to trip the clock and it restarts back to 12:00 and flashes with a beeping alarm sound. The light in the bottom oven goes on but the fan does not and the oven does not heat up. Any ideas? The oven is 5 years old. The model is DOD428"
