Product review (5 stars): Installed part quickly and washer works again!
My Whirlpool direct drive washing machine stopped working (the pump would still work to drain the water, but every time it was on an agitate or spin cycle, I would hear a load noise of the motor spinning without any movement in the tub). I took it apart and found that the coupler was broken, which after doing some research on Google, I discovered to be a common problem. I specifically ordered the non-metal version of this coupler so that the coupler would break and not the motor or the transmission! I can confirm that the coupler shipped from partshousesupply on Amazon was in fact the all-plastic model I wanted (no "a" on the end of the model number). If you'd like some help with this repair, just search Youtube for "Whirlpool coupler repair" or similar and you'll find some very helpful videos! The hardest part of the repair is definitely gaining access to the coupler. The actual repair requires only basic tools like some screwdrivers and a few common SAE sockets
