Had to replace this after our appliance suddenly stopped working properly. Mounting holes lined up correctly during install. Appliance has been running normally since then.

Used this replacement after the older unit needed replacement part. Connector alignment matched better than expected. Appliance has been running normally since then.

Ended up ordering this because the appliance suddenly stopped working properly. Fitment on our appliance was accurate. No leaks or issues noticed so far. Repair turned out easier than expected honestly.

Wasnt completely sure this would match at first since the appliance suddenly stopped working properly. Thankfully had to double check model compatibility first and everything is working again.
