Your stove will need to go on an extremely low setting - not all do. We want to see about 140 degrees Fahrenheit to complete a decent dehydration, if it goes higher you may have to throttle the oven by opening it on occasion to let heat and humidity out. If your lowest temperature on the oven is above 160 you may want to use lemon juice on the fruit to aid in prevention of burning the fruit completely. This may be acceptable for the lemons and limes - but no one wants a brown orange.
