The Trane CNT07991 integrated furnace control board functions as the central microprocessing nervous system for two-stage variable speed gas furnaces. Manufactured by Emerson Climate Technologies, this factory-certified replacement component controls power distribution across multiple system peripherals to deliver balanced airflow and high-efficiency residential heating performance.
This advanced variable control module coordinates complex heating sequences, encompassing ignitor heat-up timing, low and high-fire gas valve staging, and draft inducer motor speeds. By actively interacting with limit controls and safety switches, the board continuously protects your living environment while managing custom indoor blower operations to reduce energy draw during runtime.
Designed for direct replacement of older CNT06585 and CNT06017 boards, this 120V circuit board can be seamlessly upgraded to newer supersessions like the CNT09419 model. Professionals recommend transferring wires individually from the old terminal block to avoid layout confusion. Confirm compatibility using your specific Trane or American Standard furnace serial tags prior to purchase.
