Took around thirty minutes from start to finish while replacing the old component because the original component had worn out over time. Noise issue disappeared after replacement.

Repair Outcome

Picked this up because the original component had worn out over time. Access was a little tight behind the panel. No leaks or issues noticed so far. Packaging was decent and part arrived undamaged.

Compatibility Feedback

After dealing with a situation where the older unit needed replacement part, we installed this replacement part. Noise issue disappeared after replacement. Part quality feels reasonable compared to original one.

Installation Experience

Mounting holes lined up correctly during install while replacing the old component because the older unit needed replacement part. Appliance has been running normally since then.
