LOL! Figured as much! OK: I make a tinfoil "hood" that I place over the stovetop downdraft fan, and tuck it into the top of the oven door, held slightly open by the wooden spoon ya see there <just the handle.> That spoon keeps the door slightly open AND depresses the oven door switch, turning off the oven light, AND allows the convection <internal fan> feature to operate. I set the oven for about 125*, turn on the downdraft and away she goes. Great dehydrator!
