How to Troubleshoot & Replace Ge AP3995059 / WH43X10032 Washer Agitator Coupler

Well, I typed in the problem in google and it gave me several options or suggestions as to what might be wrong, so I dug in a littler further with the model of my washer and it came up with the coupler. So I go home, start taking my washer apart (mind you, I'm 62, stubborn, and cheap) to see if I can take it apart and I did it! I unscrewed the old coupler and it still had teeth on it, but I went with the recommendation from you guys on the coupler. So I ordered it and to my amazement, it arrived 2 days later! I put it on, screw everything back on, crossed my fingers and turned on the water. Do you know how difficult it is to see if the agitator is agitating because it shuts off when you open the hood...anyway, I heard a ton of noise (splashing noise) and took a flashlight to see if I could see the agitation and it was working! not only working, but REALLY working. I was SO proud of myself. Called myself Ms. Maytag washer repair person for a few days. Anyway, I so appreciate your help with helping me figure out what the issue was, showing me pictures and most of all, getting it to me in two days! I would HIGHLY recommend you to anyone! Thank you so much! 

I had to remove the agitator to unwrap the string. In the process, aparently I did not get the agitator installed back on the coupling properly. It came off the adaptor during the spin cycle so i reinstalled it. Severa days later someting else got wrapped around the coupling causing the agitator to come off atgain durng the high speed spin cycle. ( Made quite a noise.) Only the top of the agitator was damaged so I have been able to reuse it.. On ispectiion I noticed that the coupling was eamaged (split). Installing the new coupling agitator was easy as the agitator was off. Everyting is reinstalled and seems to be working fine. 

My husband put the new agitator together and it is working great, thanks for having all the part I needed. Susie 

I searched the web to see how to fix it and what parts I needed and came across Appliancepartspro and saw thier how to videos. I watched the videos, which were simple, straight forward and easy to follow. The price of the parts were cheaper then my usual appliance parts store too. I went ahead and ordered from here and the parts came in 2 days with regular shipping. I was able to fix the washer in 15 min. 

AppliancePartsPros sold me a new agitator. The agitator and agitator coupler have plastic splines and they get worn over time. I originally thought that metal splines would last longer, but if something in the washer tub gets tangled around the agitator, if the machine had metal splines then the transmission under the agitator would be ruined prematurely. It will wear out soon also but not right now. If you don't replace the coupler and agitator when they begin to wobble and rumble then the splines will strip and then you can order the parts in a hurry. I try to stay up with my to do list. It helps if you are the one who does some washing of clothes. Our wives may not tell us about a wobble. They will tell that the washer doesn't work. 

Took the old one off, put the new one on. Agitator arm had to come off first, which was easy since it was flying off during agitation cycle. Found some inner grooves on the arm are worn so maybe will replace whole lot sooner than expected. 

Me watching your video help a lot, and easy buying it.
