    🛠️ HVAC Depot Pro Tip

    Important: CNT07943 has been associated with a furnace ignition-system upgrade. If replacing an older CNT07679 board, verify whether the required ignition upgrade kit has already been installed. A board-only replacement may not be appropriate for every furnace.

     

    Equipment / Model Compatibility

    Compatible with select Trane and American Standard single-stage gas furnaces using the specified IFC ignition system. Verify the furnace model, serial number, ignitor configuration, and approved replacement kit before installation
