I ordered an Infinite Control Switch from AppliancePartsPros.com.com. The part came in two days. I removed the top access panel from the back of the range. Pulled the knob off of the front panel. Took out two screws holding the switch in the unit. I pulled the old switch out just a little. Held the new switch beside it and removed the wires one at a time to the new switch. Put the switch back in place. Put in the screws. Put the knob back on. Plugged the range back in and tried it out. Bam ! Success!
