We were preparing a meal and put some food into this oven. When I turned it on everything (control, lights, etc) went off. I checked and the outlet into which it was plugged was still working and another item plugged into it was still working properly. I couldn't locate the manual (in English) for this model, although I did find 2 copies in Spanish. We were enjoying using this piece of equipment and hope we can obtain another copy of the operating manual for it.
