Genuine Trane Part
This turned out to be a genuine Trane part, as advertised, not a similar 3rd-party generic part. That was important to me, because I was fixing a 33 year old gas furnace in the middle of winter, with everyone in my household waiting on me to fix the heat, and I wanted the correct part the first time, not generic 3rd-party guesswork. I am happy to report that our 33 year old Trane XE 80 is now back to running as good as new. The wiring terminals are in different places on this upgraded modern part, but this is the exact correct factory part designed by Trane to supersede the original 1992 part number, and it functions perfectly, exactly like original part.

Needed transformer asap
Had a power surge and it blew my transformer and board on my Trane furnace. Part fit perfectly, plug and play. Fast shipping.
