Repair Outcome
5
Fitment on our appliance was accurate while replacing the old component because the appliance suddenly stopped working properly. Noise issue disappeared after replacement.

Installation Experience
4
The original component had worn out over time on our appliance ended up being caused by a failing part. Connector alignment matched better than expected and the replacement solved it.
