Excellent repair Terry!!!!
I was trying to get all the info together to give you the exact advice you figured out on your own.
I did some failure analysis on three of these door lock/switchs. I've replaced 3 in the last 30 days that where just between 1 and 2 years old with the same problem. Out of three of the wax motors, 2 of them checked ok electrically and when I disassembled the wax motor and ran it without the heavy spring, the plunger just barely pushed out in one and came out all the way in the other but was very easily pushed back in with a screwdriver. The third one the little wax mechanism was totally rusted and so enough power couldn't get thru it and it showed no continuity but did heat up slightly.
I've actually never seen any of the contact points in these switches fail only the wax motors. The wax motor is not listed separate so no way to get it unless you figure out like you did. If you can find the correct wax motor as you did that would be the fix I would do for my customers instead of charging $48.95 for a complete new lock assembly just replace the wax motor at a cost of less then $20.
I found that exact same wax motor on a door from a Maytag dishwasher at the scrapyard and didn't have a model# it came from, the part# 6914116 is stamped on the part and on the picture you refered to at RepairClinc doesn't come up anywhere as a good number, (Note: the one you found is electrically rated and shape and size is exact, the only difference is the the part manufactures OEM part# on the wax motor out of the Frigidarire locks is labeled 11176-63 and the one you found which is in the Maytag dishwashers dispenser is 11176-61).
Thank you for posting the original Maytag wax motor part#, that has helped me greatly.
And as far as testing goes, you could have tested, machine didn't have to be spinning to do test, in the last spin cycle the wax motor is energized as soon as the pump starts pumping, it takes about 1 1/2 minutes for the wax motor to activate if it is working correctly, (I always give it at least 2 minutes), then unplug the machine and try to open door. If the door opens the wax motor is bad,(that is if it was getting power, you would need to check to be sure), otherwise it will take about 2 minutes before you can open the door, the time it takes for the wax motor to cool down and go back to it's normal resting state.
