Replaced temperature sensor. Was hoping I could replace it from the front, but this unit required pulling the oven from the cabinet. We placed a couple of concrete cinder blocks on a rug in front of the ovens and rested the front of the unit on those as I worked on the back side. We left the wiring attached to the wall, since the breaker was turned off and we could not really reach the wall behind the ovens, anyway. I am a 56 yr old woman, so I had two of my college sons muscle the ovens out of the cabinet for me after I removed both doors. Double wall ovens are pretty heavy, but the actual replacement of the temperature sensor was the easiest part. LOVE the helpful installation video on your web site. Thank you.
