Trane CNT07943 Control Circuit Board

Trane CNT07943 Control Circuit Board

This board was part of a stability upgrade that increased the voltage limit to 120V on numerous Trane systems.

If your system has already had that upgrade kit previously installed (this board + ignitor in KIT*****) and your board has failed, you can replace just this board. If you have not purchased or had the upgrade kit installed, you will need to call us with your model and serial from the inside wall of your unit to see which kit is needed.

Previous board number was CNT07679 which is in KIT18109.
