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.

Repair Outcome

Mounting holes lined up correctly during install while replacing the old component cause the appliance suddenly stopped working properly. Everything powered back on correctly afterward.
