Just got this unit. In a nutshell, the coupling on the motor driven shaft for the ice maker is not turning the auger to force ice out. All electrical parts work and nothing is stuck. When I activate ice dispenser with door open and tray out all works fine, but as soon as you put any force on the metal coupling it just spins freely on the shaft. SHaft is threaded and seems like there should be a nut on it to hold coupling tight??? I tried several sizes the other day to see if that worked but none fit. Is there supposed to be a nut on this threaded shaft to hold coupling down? Anyone know what size it is? Thanks for any help.

#9 is threaded onto the auger motor shaft so I would order that part Hope this helps

From what I know the coupling is threaded onto the auger motor shaft if yours is spinning freely on it that would tell me it is stripped out or the threads on the auger motor are bad. Whirlpool as been threading that coupler onto the shaft for many years I also think they are left handed threads

I cannot get the coupling off it just spins. So if the threads are stripped will I have to replace the whole motor? Seeing as how the threads on the motor shaft would probably be messed up as well? Or is the shaft that I see actually threaded onto another shaft on the motor? Thanks very much for trying to help me. I guess since its only a couple months old I should just have a repairman do it. It has a one-year warranty. it should be covered??? Right?

I have the same problem. I think the motor is okay. but the coupler spins freely. How do I get the old coupler off?
