York S1-363-90016-702 Heat Exchanger

The York S1-363-90016-702 Heat Exchanger is an essential OEM replacement component engineered for high-efficiency thermal transfer in York gas furnaces and packaged HVAC units. This 5-tube heat exchanger assembly is constructed from heavy-duty aluminized steel to resist oxidation and thermal fatigue, ensuring long-term structural integrity under high-demand cycles. As a veteran-grade HVAC replacement part, it utilizes a precision-engineered tubular design that maximizes surface area contact, facilitating optimal heat transition from combustion gases to the circulating airflow. Specifically designed to fit York B1HN series units and other compatible PCE4 models, this assembly includes integrated baffles to mitigate resonance and vibration, which are primary factors in premature metal stress. When diagnosing a cracked exchanger or restricted airflow, installing this genuine S1-363-90016-702 assembly restores factory-spec combustion safety and system efficiency. Given its 144 lb. industrial build, this primary heat exchanger ensures the reliable separation of flue gases from the home’s breathing air.

• OEM Precision Fit: Engineered directly by York/Johnson Controls to match existing mounting brackets and burner alignments in 5-tube furnace configurations.
• Enhanced Durability: Constructed with thick-gauge aluminized materials to withstand 350°F operating temperatures and up to 200 psi pressure variables.
• Vibration Dampening: Internal baffles reduce acoustic resonance and mechanical stress, protecting against common weld-point failures.
• High-Efficiency Transfer: Optimized gas-flow pathing ensures maximum BTU extraction for improved seasonal energy ratings.

• What units is the S1-363-90016-702 compatible with? This 5-tube assembly is primarily used in York packaged units and gas furnaces, specifically compatible with series like the B1HN090N16525 and select PCE4 14 SEER models.
• How do I identify a failed heat exchanger during a service call? Techs should look for erratic flame patterns (flame rollout) when the blower kicks on, excessive rust flakes in the burner compartment, or use a combustion analyzer to detect CO leakage.
• Does this include the secondary heat exchanger for high-efficiency models? This part number typically refers to the primary tubular assembly; verify your specific model's bill of materials for secondary cell requirements.
