Installed this when the older unit needed replacement part. Had to double check model compatibility first. Everything powered back on correctly afterward.

Wasnt completely sure this would match at first since the appliance suddenly stopped working properly. Thankfully access was a little tight behind the panel and everything is working again.

The older unit needed replacement part on our appliance ended up being caused by a failing part. Fitment on our appliance was accurate and the replacement solved it.

Picked this up because the appliance suddenly stopped working properly. Needed basic hand tools only. Unit completed a full cycle without issues. Part quality feels reasonable compared to original one.
