How to Troubleshoot & Replace Whirlpool AP6006687 / WP2220458 Refrigerator Ice Maker Drive Coupling

The problem was that the motor coupler & shaft had a tiny bit of rust at their union. With the weight of the ice bin it rusted in the lowest position. This didn't allow the motor coupler to float on the shaft. There is a spring inside the shaft that pushes up on the motor coupler keeping it engaged in the ice bin coupler above. This coupler in turn rotates the auger in the bin to dispense the ice. I removed the motor coupler & shaft, tapped the coupler loose and filed off the rust. This allowed everything to work perfect but since I had purchased a new coupler, spring, seal and washer I replaced them also. Trick to save time: remove the ice bin, push down on the coupler still in the door. It should depress maybe 1/4". If it does check the coupler in the ice bin. If is doesn't, disassemble the coupler/shaft and see if the above happened to you. 

When you pressed the ice maker you could hear the motor but it would not crush the ice, I ordered the shaft and teh spring, but it still would not work, we looked at the motor and the spot where the shaft fits was stripped. I ordered the new motor, and that was it. Both types of ice. 

Changed the couplings took about 5 minutes 

New auger motor, shaft, and washer fixed it for about $120 , repair people quoted $500 

I replaced the ice maker assembly with a new unit. I had to replace the motor, the drive shaft, the coupling and seal and washer for the ice assembly unit. The videos were quite helpful and everything installed quite easily and all working perfectly. You guys do a great job! 

There is a hexagonal shaft that connects the ice dispenser motor to an auger/chopper in the ice hopper. The end of the shaft had rounded-off. A new shaft was needed to fix the problem, but I realized that the real problem was that only about 1/8" of the shaft actually engaged the auger coupling at the top end. I needed to raise the shaft a little to make it better engage, so I dropped 4 #6 washers into the motor socket which raised the shaft about another 1/8", giving it about 1/4" engagement into the auger coupling at the top while maintaining about 1/2" engagement into the motor socket at the bottom.

Found motor coupling is worn out and replaced same with part # AP6006687 

New coupling 

It was a good experience and the repair only took 20 minutes or so. I ordered both couplings, the one on the door and the one on the ice maker. When I removed the coupling from the door I could see why the coupling was worn. The spring which keeps the coupling engaged was jammed. So just making sure the spring was working and replacing the one coupler did the trick.
