Replacement Observation

The appliance suddenly stopped working properly on our appliance ended up being caused by a failing part. Mounting holes lined up correctly during install and the replacement solved it.

Installation Experience

Wasnt completely sure this would match at first since the older unit needed replacement part. Thankfully mounting holes lined up correctly during install and everything is working again.
