This part is the replacement jar or cup for your blender. This assembly contains the blade and the jar. It is made of clear plastic with a black plastic handle, a white plastic base, and a metal blade...
I decided to see if I could dislodge the faulty coupling. I placed a screw driver under the coupling and pushed up. It dislodged. Subsequently I found a youtube video that indicated that was exactly what I should do. I ordered the part from parts select and placed the coupling on my blender. It screws in counterclockwise. It works fine. I am very satisfied.
Very simple I turn off the Refrigerator and disconnect the bad ice maker, removed the part. I connect the replacement parts and voila the ice maker been making ice same that day.
