York S1-363-93846-704 Heat Exchanger

The York S1-363-93846-704 is a heavy-duty, 8-Burner Heat Exchanger designed for reliable thermal transfer in high-capacity York HVAC units. Engineered to handle the rigorous heating demands of large-scale systems, this OEM replacement part ensures precise combustion-to-air heat distribution via its eight 24V furnace burner tubes. Constructed with durability in mind, its rack-mount configuration facilitates a stable fit within the cabinet, preventing vibration-related fatigue and minimizing the risk of cracked heat exchanger symptoms, such as rollout or CO leaks. For technicians servicing commercial or larger residential platforms, this direct-fit OEM component is essential for restoring system efficiency and peak output. This 43-7/8" tall unit is built to withstand thermal expansion cycles without compromising structural integrity. Whether you are performing a mid-season York furnace repair or a proactive system overhaul, this assembly provides the exact specifications required to maintain factory-grade performance and safety standards across all compatible Johnson Controls equipment.

• Optimized Thermal Transfer: The 8-burner configuration maximizes surface area contact to ensure high-efficiency heat exchange.
• Precision OEM Fit: Specifically engineered for York S1-363-93846-704 compatibility, reducing labor hours and installation complexity.
• Industrial-Grade Build: Heavy-duty materials resist corrosion and pinhole leaks commonly found in aging aftermarket alternatives.
• Enhanced Safety: Designed to maintain strict combustion boundaries, protecting the indoor air stream from exhaust gases.

What are the signs that a York heat exchanger needs replacement?
Technicians should look for soot buildup, visible cracks, rusted-out pinholes on the first pass, or fluctuating flame patterns when the blower kicks on, which indicates a breach in the exchanger wall.

Is the S1-363-93846-704 compatible with my specific furnace?
This 8-burner assembly is designed for specific high-output York and Johnson Controls models. Always verify the model and serial number on the unit data plate to confirm the correct part number match.

What components should be inspected during an exchanger swap?
When installing a new heat exchanger, it is standard practice to inspect the burner orifices, flame sensor, igniter, and inducer blower for wear or obstruction to ensure the entire combustion system operates correctly.
