How to Troubleshoot & Replace Whirlpool AP6011291 / WP7403P239-60 Infinite Switch Top Burner Control Switch

I replaced the front burner control (2nd time) to fix this. The repair was easy, and works fine now. 

Replaced burner control. 

Replaced the switch 

Changed the infinite switch. 

To fix the oven temp running out of control, I replaced the thermostat. This was a fairly easy process. Turned the breaker off at the breaker box, then unplugged the stove. Unscrewed and took off the back panel. Removed the knob that controls the stove (just pull it off). Unscrewed 2 screws that held the thermostat in place. Oriented the new thermostat so it was the same direction as the old one, then removed the wire connections (just pull with a pair of needle nose pliers) from the old thermostat and attached them to the new thermostat one at a time. Removed the back right burner (just pulled it out) and lifted the top (where the burners are located) so you can pull the temperature sensor up through the hole that was under the burner. Then inserted the new temperature sensor through the hole and placed it where the old one was. Screw the new thermostat back in place, replace the burner I pulled out, drop the top back down and put the knob back on. It was a similar method for replacing the switch for the large burner. Pull the knob off, unscrew the switch. Orient the new switch. Remove wire connections from old switch and move to new switch, one at a time. Screw new switch back into place, replace the knob and replace the back panel. Then plug the stove back in and flip the breaker switch back on. 

Replaced control switch. 

Looked on this website for troubleshooting, went to parts site, put model number in and figured out the part I needed, watched video and ordered part. It took 10 days to get my part but was able to track it easily. It could have been packaged better, but was not damaged. 

Ordered part and replaced, no problems after watching the video. 

Took screws off back panel and changed switch part. Easy!!! 

Replaced control switch. Tools required, needle nose pliers, phillips head screw driver, pencil and paper. Disconnect power supply to stove. Remove the screws holding the control panel (two screws in front under the panel at each end) 4 screws in back. Lay control panel over stove top. Hold new switch up and make sure the electrical spade connectors are in the same location. Make a drawing on paper where the Red wires (single wires) and black wire (single wires) and Red wire series wires and Black wire series wires are. This will be your back up in case you get mixed up which wire went where. Use the needle nose pliers and remove all the wires from the switch. Remove the two mounting screws from the front of the switch, remove switch. Reverse order to install.
