Pulled out stove, unplugged it. Removed back 4-1/4 inch screws, removed safety panel. Took picture of control switches. Removed knob, took out 2 screws holding control switch on front. Pulled out control and removed wires one at a time. Put corresponding wires on new control one at a time. Did the same procedure on the other control. Reattached controls and put safety panel back on. Put knobs back on, one was a little stubborn to put back. Plugged stove back in, tested small burner and everything was fine. Turned on large burner seemed backwards. I then thought about the trouble to put this knob back on. Found out knob was put on upside down. Put knob back correctly stove is like brand new.
