After dealing with a situation where the appliance suddenly stopped working properly, we installed this replacement part. Unit completed a full cycle without issues. Packaging was decent and part arrived undamaged.

Had to double check model compatibility first while replacing the old component because the appliance suddenly stopped working properly. Repair solved the original problem.

Ended up ordering this because the older unit needed replacement part. Took around thirty minutes from start to finish. Noise issue disappeared after replacement. Packaging was decent and part arrived undamaged.
