Compatibility Feedback

The original component had worn out over time on our appliance ended up being caused by a failing part. Installation wasnt too difficult overall and the replacement solved it.

Helpful Product Insight

Wasnt completely sure this would match at first since the older unit needed replacement part. Thankfully fitment on our appliance was accurate and everything is working again.

Repair Note

Ended up ordering this because the older unit needed replacement part. Mounting holes lined up correctly during install. Appliance has been running normally since then. Part quality feels reasonable compared to original one.
