Replaced the burner Infinite switches for the burners having the issue. Here are the latest part numbers for this model Maytag. Left rear (LR) and right rear (RR) burners are both 6" and use the same switch. Part # WP3149404. Left front (LF) is an 11 1/2" burner Part# W10167742. The right front (RF) burner is a double burner 6" center and 9 1/2" outside burner Part #WPW10149355. Very simple repair. Unplug the stove, remove the rear panel, remove the switch knob, remove the 2 switch screws, unplug the 2 wire connectors. The 2 wire connectors were pretty tight so I just used a small flat-tipped screwdriver to gently pry each corner of the connector until it popped loose. Reverse procedures. The only snafu was the switch for the 6" burners #WP3149404 have an extra long switch shaft to accommodate other model stoves that must be snapped off to shorten the length so that the knob will fit as it should. Simply remove the little black clip, hold the switch shaft with a pair of needle-nose pliers as close to the switch as possible, take a pair of regular pliers, and remove the outer end section by wiggling it back and forth until it snaps off. Reinstall the black clip in the rearmost groove and install the knob. I did this with the switch installed and it was really simple. There are no included instructions to tell you this so I was thinking I got the wrong switch, not the case. I called Appliance Parts Pro and they said that there is a video online that shows how to do this. For some, just looking at it you can figure it out. This procedure for snapping off the switch shaft applies to my model Maytag but may not apply to other models or brands. Check your original switch shaft length before you go through this procedure.
