York S1-373-19870-502 Blower Housing

The York S1-373-19870-502 Blower Housing is a precision-engineered OEM replacement part designed for high-static pressure furnace applications. Built to exact 11x11 metal specifications, this housing is a critical component for maintaining the structural integrity and airflow dynamics of York gas furnaces. It is identical to former part number 373-19870-502, ensuring a direct fit for units like the GY8S series, including 100, 115, and 130 MBH models. For a technician, this housing is the primary solution for resolving excessive vibration, resonance, or airflow restriction caused by damaged or warped factory enclosures. By housing the blower wheel securely, it optimizes the HVAC blower assembly performance, maximizing CFM delivery across heat exchangers while protecting the motor from debris. Proper replacement of the York furnace blower housing restores factory-standard discharge patterns, which is essential for preventing premature heat exchanger fatigue and ensuring consistent static pressure throughout the duct system.

• Factory-Grade Alignment: This genuine York part eliminates the mounting difficulties often associated with universal aftermarket housings.
• Enhanced Airflow Efficiency: Optimized internal curvature reduces turbulence and stabilizes furnace static pressure.
• Model-Specific Compatibility: Drop-in replacement for York GY8S100C20DH11C, GY8S115C20DN11C, and GY8S130D20DH11C systems.
• Structural Durability: Heavy-gauge metal construction prevents housing flex and decreases mechanical noise during high-speed operation.
• Direct Cross-Reference: Fully compatible with legacy part number 373-19870-502 for seamless inventory management.

What causes a blower housing to need replacement?
Mechanical failure is usually driven by a detached or unbalanced blower wheel impacting the internal walls, lead-in corrosion from secondary heat exchanger leaks, or structural fatigue causing excessive vibration.

Is this housing compatible with non-York residential units?
This part is specifically engineered for York, Luxaire, and Coleman equipment. Always verify the furnace blower housing dimensions and mounting bolt patterns against your specific model serial number.

Does this part include the blower motor or wheel?
No, the S1-373-19870-502 is the metal housing only. The blower motor and wheel must be ordered separately or salvaged from the existing assembly if they remain within tolerance.
