Cut off power at fuse panel. pulled stove out from wall went behind stove removed back panels in area of sensor that I could see from the front side, inside oven. Located sensor from rear & unpluged senser from wiring bundle reached inside oven & removed screws from sensor. Pulled sensor out & threaded wire through hole. Took old & new sensors to bench in shop. Plug on new not the same as old. Had to change plug Cut and stripped wires. Wire is very small, need to use a good stripper. Twisted wire together & soldered connection, used shrink wrap to insulate wire. Took part inside and reinstalled in reverse order. Used 1/4 inch nutdriver on total job start to finish.
First we removed two screws under the rim of the range top to open the lid. Lifted the lid and removed the screws from the bracket that holds the elements, Be careful with the clips that hold the element in, if you break them or bend them there aren't any more! Also note which holes they were in, they are marked according to the different sizes of elements. Disconnected the wires, needed needlenose pliers to grip them...connected new element, popped it back in place, replaced bracket, closed top ...Easy peasy!!!
I called a repair place. They charged $54 to diagnose, (said it needed a new latch motor) then wanted $220 to complete the repair. I checked online prices and did it myself for about 15 minutes work and the latch motor itself ($44?).
Was necessary to uplug the range, pull it away from the wall and remove the back panel sheet metal, then 3 screws that mount the motor. Replace motor, reattach sheet metal. Plug in. Done. Ready to bake cookies.
