York S1-026-37407-000 Control Board

The York S1-026-37407-000 Fan Timer Control Board is a critical OEM component designed for precise blower motor management in upflow and horizontal oil-fired furnaces. As the primary HVAC control board for your heating system, this module regulates air handler timing to maintain safe internal temperatures and optimize airflow efficiency. This genuine York furnace replacement part acts as the central logic unit, coordinating the post-purge cycle after burner shutdown to dissipate residual heat and protect the heat exchanger from thermal stress.

Engineers and technicians rely on the S1-026-37407-000 to address common system failures, such as a furnace blower motor running constantly or inconsistent fan cycling. By replacing an obsolete or malfunctioning fan timer control board with this upgraded Source1 part, you ensure direct compatibility with York, Coleman, and Luxaire equipment without the need for field modifications. This 120VAC board is engineered for high-duty cycles and provides consistent voltage distribution to the blower assembly, preventing the overheating issues associated with aging relay components.

Key Benefits:

• Direct OEM Replacement: Seamlessly replaces older part numbers and obsolete control boards (including 29388 and 026-37407-000) for simplified field installation.
• Extended System Lifespan: Precision fan delay timing reduces thermal fatigue on the heat exchanger and motor windings by ensuring complete heat dissipation.
• Universal Compatibility: Engineered for use in York, Coleman, and Luxaire horizontal oil-fired furnace applications.
• Enhanced Diagnostic Capability: Designed to integrate with existing furnace safety circuits, facilitating easier troubleshooting of short-cycling and limit switch trips.

Common Questions:

What are the signs of a failing York fan timer control board?
Common symptoms include a blower fan that won't turn off, intermittent motor operation, or the furnace shutting down prematurely due to lack of airflow coordination after the heating cycle ends.

Is this board compatible with multi-stage air handlers?
The S1-026-37407-000 is specifically mapped for upflow and horizontal oil-fired furnace configurations requiring accurate fan timing; always verify the furnace model number against the manufacturer specifications for multi-speed compatibility.

Does this replace the 146039 control board?
Yes, this York S1-026-37407-000 is the direct replacement part for the 146039 series often found in residential heating units.
