SAFETY first- I shutoff power before doing anything with the stove.
The main problem was the pull the stove from the wall.
After that replacement of infinite switches was simple.
Just had to match the contact’s label on the old switch with new and swap wire between them.
Also, the new switch was in some ON position, so I attached the knob and turned until it clicked to off position.
Then removed the knob & installed the switch so the found off position and off position label on the rear guard matched.
Also, I used cut-proof gloves. Easy to get cuts removing/installing back wall.
When swapping wires to the new switch, I pulled only at the connector the wire is attached to, not the wire itself.
