Trane CNT 03457 ignition module
More Details
After searching, found this was the proper part, received quickly and is now working, thanks Keith specialty!!
This ignition module was an exact replacement for an old CNT1634. It was easy to install and purchased with the Trane Kit 06839. It worked just as advertised.
Ordered board and conversation kit/wire harness. Product came in, installed it that night after work in the dark. It was plug and play for my unit. Works great and great price. Happy family that heater is up and running again! Replaced CNT01669 Board, 2 stage furnace.
Purchased the board on Monday and had it to install on Wednesday just before the next cold blast hit. It worked great. No problems.
Came with great instructions worked perfect.
I needed this for my older Trane unit. The CPU board (CNT-1634) died on me Thanksgiving day. I ordered this new replacement board that night from Keith's along with the conversion kit (KIT-06839). They shipped it on "Black Friday" and I received it the following Monday and I live in TN. Thank you for great service and a great price!
