Removed the large lower back panel of range (6-8 phillips screws) which holds upper control back panel in place. Removed upper control back panel (2 screws), exposing infinite switch electrical connections. At front face of control panel, removed (pulled off) control knob, exposing 2 phillips screws holding switch in place. (NOTE: A sleeve is on the switch arm or maybe remains inside the control knob). Look for this sleeve. Without it, the knob will NOT seize the switch rotary arm.
Removed each wire connection individually, one at a time, installing it in the proper position on the new switch.
Reverse all procedures to put things back together. A very simple, straight-forward operation.
