Carrier 334357-751 Heat Exchanger

The Carrier 334357-751 Heat Exchanger is an OEM Carrier secondary condensing heat exchanger designed for 90% AFUE and higher gas furnaces. This 15-cell assembly is critical for capturing latent heat from combustion gases, significantly increasing thermal efficiency in Carrier, Bryant, and Payne furnaces. Engineered with high-grade, corrosion-resistant materials, this replacement heat exchanger is built to withstand the acidic condensate produced during the combustion process. It serves as a direct drop-in for 58MXA, 58MSA, and 58MVC furnace series, ensuring precise fitment and restoring the system's factory performance levels. For technicians performing a furnace heat exchanger replacement, this kit typically includes the necessary gaskets and mounting hardware to secure the cell panel assembly. This component is essential for resolving common secondary-cell failures such as clogging, delamination, or breach, which can lead to inducer pressure switch trips or rollout limit openings. Professional installation is required to maintain proper manifold pressure and vent integrity.
