York S1-363-90016-703 Heat Exchanger

The York S1-363-90016-703 Heat Exchanger is an OEM replacement part engineered for high-efficiency residential HVAC systems. This heavy-duty 5-tube heat exchanger is constructed from aluminized steel to provide superior thermal conductivity and resistance to the corrosive effects of combustion gases. Designed for multi-position furnace configurations, it facilitates precise heat transfer between the burner assembly and the circulating air stream, ensuring your system maintains peak AFUE ratings. Weighing approximately 163 lbs, this robust assembly is built to withstand the rigorous thermal expansion and contraction cycles found in modern condensing furnaces. Utilizing a tubular design helps minimize the internal stresses that typically lead to heat exchanger failure or cracks. When performing a furnace heat exchanger replacement, verify the part number S1-363-90016-703 against your unit's data plate to ensure a seamless fit with the factory collector box and inducer motor assembly.

Key Benefits

• Factory OEM Precision: Eliminates alignment issues during the HVAC installation process, fitting existing mounting points without modification.
• Enhanced Thermal Exchange: The 5-tube configuration optimizes surface area contact for rapid heating and high energy efficiency.
• Durable Aluminized Construction: Resists fouling and corrosion from moisture and household chemicals.
• Universal Compatibility: Engineered for use in York, Coleman, and Luxaire residential heating equipment.

Common Questions

What are the signs that my current heat exchanger is failing?
Technicians look for five-flash fault codes (rollout switch), soot production, or visible cracks in the heat exchanger tubes. Unusual smells or frequent short-cycling can also indicate a compromised unit.

Is this a primary or secondary heat exchanger?
The S1-363-90016-703 is a primary aluminized tubular heat exchanger designed to handle high-temperature combustion directly from the burners.
