Product review (5 stars): Worst case scenario was that we were wrong
New life to an aging ac unit. After watching many utube videos and searching the forums, we decided to trt this after our blower fan in our 20 year old trane unit stopped turning. Worst case scenario was that we were wrong, and the fan unit needed to be replaced. But apparently this relay is a common source of failure. Armed with a screwdriver, a schematic, and a flashlight, we were able to replace the old module with this upgraded relay. And a sigh of relief as the fan kicked in and blew its first cool breath to welcome spring. Highly recommend for those brave diyers who have been told thier unit should just be replaced. This will not cure all, but is a proper replacement for a failed part.
