After looking on YouTube we saw videos of the required fix. AppliancePartsPros.com had a very good video which explained the part needed and the process. They also have a part look up based and your model number which is very helpful. My husband replaced the MWF Assembly Manifold today and so far, we have water, ice and no weird sound!
The part # AP6891555 (WR17X22074) was reasonably priced as well. Thank you so much.
