How to Troubleshoot & Replace Whirlpool AP6050116 / W10900107 Infinite Switch

Ordered limit switch and replaced. Worked! 

Replace 1 switch, 2 burner receptacle plugs, and 2 8" burners. Range is 35 years old, but still works good. Now it works better. 

Turn off electricity to stove!! Unscrew top of range. Unplug bad part and replace with new part. 

Watched the video on the page with the part and the repair was quick and easy. 

After some back and forth with the wife about whether or not to replace a 30 year old cook top stove with two non functioning burners, the cost to replace with a brand new stove would've been too much not to mention all new cooktops require 40A or 50A source breakers which ours is only 30A. This is kind of hard to mitigate when our cooktop is on an island on the opposite side of the house with a story above us and a solid concrete foundation. So better for now to fix it with a simple Rheostat and receptacle fix after doing some googling on how simple it is to fix those specific problems. I hope the stove last up until we finally decide to remodel the kitchen. This website was helpful in that it provided the manuals in order to specify what parts were required (including equivalent rheostat) to repair our cooktop. 

I replaced the infinite control switch. I had replaced all the switches 5 years ago (I mark the replacement date on the new parts with a Sharpie). I watched the replacement video anyway, however, and it is an excellent piece. Having done this before, it was a relatively simple job. The hardest part was sliding the range out of its "nook"! This range only had a small upper cover behind the control panel with 5 screws. I UNPLUGGED the range, removed the 5 screws, removed the knob and the screws mounting the switch at the front. I replaced the 5 wires one-by-one. The long shaft for the knob on the front had to be placed through the hole in the panel before swapping the wires because the wires have no slack and can't be moved out far enough to allow the long shaft to be inserted. I made sure all the wires were securely attached and reinstalled everything as it was. It required 2 pairs of pliers to break the shaft off to the correct length. You gotta be sure of your length before you break! You only have one shot at this-measure with the knob first to see how much to break off. The new switch works great and it functions more smoothly than the old one ever did. Thanks Appliance Pros! 

Just took the replacement part and installed it Piece of cake job 

Parts were as advertised. Quick and Easy fix. Parts arrived the next day after ordering. Will be repeat customer. 

Replaced worn out knobs,burners and receptacles,and an indicator light. Easy fixes, range looks new again. 

Replaced the surface unit switch, and that fixed it.
