I removed screws that hold cover and put cover aside. I removed the buttons and removed glass cover. I pulled panel out far enough t get tswitch wires and installed switch. Be very careful not to let wires touch metal.
The replacement switch was slightly larger than the old one so it would not go through the hole in the front panel so I had to get a reaming tool and enlarge the hole just a little for the switch to go through. It was still an easy repair as I had the proper tool.
I removed the screws holding the bezel, removed the control panel frame, unhooked the four wires from the timer, and removed the timer. I cut the glue holding the circuit board into the frame and removed the circuit board. I unsoldered the faulty encoder switch, dissassembled the switch, determined the correct specifications for the swit
... Read morech, and ordered the nearest equivalent from an electronics supplier. I modified the new encoder to accept the shaft from the old encoder and I re-drilled the circuit board to fit the new encoder. I then soldered and wired the encoder, reversing the wires to correct the direction of rotation. I then reinstalled everything and added the knob purchased from partselect.com. Now it works. Tough repair - not for the faint of heart or those of average skill. But for the record, installing the knob was of course child's play and took only a moment.
