Hello all,

I have a Trane TUE080A936K3 and I am trying to find a replacement control module. I had a professional come out and tell me that mine was shot (blower would not start) and he has never been back to replace it so I would like to purchase it myself and reinstall it.

The control module Trane part number is CNT 2789 and White-Rodgers number 50A55-571. I think I have found two different replacements at two different price points: Trane CNT 03797/White-Rodgers 50A55-486-04 at $96 or the White-Rodgers 50A55-843 at $93. Both say they replace my original board.

Is there a major difference between the two? Which is the correct one to purchase?

Any advice is appreciated. Thanks in advance.
