I simply looked at the new switch , to see how it fastened in the stove. It had plastic clips that were easily depressed to allow the swithch to be removed. I removed it , (after turning the circuit breaker off to the stove) removed the three wires , and replace them on the new switch and simply pushed it in the space. It snapped in place , and the job was done . Works great!
It is really easy to replace IF you know that the tabs that hold the switch in are ON THE TOP AND NOT ON THE SIDES. I wasted a lot of time prying on the sides to get the switch out. It would have been really easy if I had known the tabs were on the top and bottom.
