Looking at two threads that have a DE712 dryer, it looks like both are electronic control dry. The 712 has 3 temps--regular, delicate, and air fluff as well as variable end of cycle signal There's also a start button. The timer dial controls degree of dryness and and perm press cycle has extended tumble press care. I found a basic control panel sketch on sears downloaded manuals and I had friends that had the LDE713. The panel had the same buttons for heat levels. There was also the start button and cycle signal level adjustment. The degree of dryness was also on the panel with three buttons--less dry, regular dry, and more dry. The cycle control dial has a "start" position for both the regular and perm press cycles. The press care on this dryer was optional at the end of the perm press cycle. the press care segment on both dryer models also served as the air fluff segment on the timer dial. All to the best of my recollection. My friends that had the LDE713 dryer originally had a set from the late 1970s that was an A407 fabric matic washer and DE606 big load electronic control dryer. The LDE713 replaced that dryer. They called me in like 2008 or 2010 asking for a suggestion to what they would replace their dryer with. I begged them to have the dryer repaired but they wanted a new one. They ended up with a Maytag branded whirlpool dryer.
