York S1-031-09170-000 Control Board

As a seasoned technician, you know that a failing defrost cycle is a quick way to kill a heat pump's efficiency and risk compressor floodback in freezing conditions. The York S1-031-09170-000 Control Board is the precise OEM replacement required to restore factory-spec timing and temperature monitoring for your defrost sequences. This defrost control board is engineered specifically for York, Coleman, and Luxaire heat pump units, serving as the "brain" that coordinates between the ambient sensors and the reversing valve to clear coil frost effectively.

The S1-031-09170-000 is an upgraded Source1 component, ensuring that the logic matches original system requirements for voltage distribution and safety switch monitoring. Whether you are servicing a York heat pump control board in a residential split system or a light commercial unit like the BP060 series, this board provides the exact terminal compatibility and mounting footprint needed for a clean, professional install without field modifications. For contractors, using this genuine York replacement part means fewer callbacks and a system that operates at peak SEER/HSPF ratings even in extreme cold-weather applications.

• Optimized Defrost Cycles: Prevents excessive ice buildup on outdoor coils, maintaining heat transfer efficiency and reducing mechanical stress.
• OEM Precision: Direct replacement for the 031-09170-000, ensuring the logic-gate timing aligns perfectly with your specific York or Coleman model.
• Advanced Diagnostics: On-board logic assists in monitoring system sensors, allowing for more accurate troubleshooting of defrost issues in the field.
• Enhanced Durability: Constructed to withstand the thermal cycling and moisture typical of outdoor condenser environments.
• Broad Compatibility: Fits various York HVAC systems, including high-performance heat pumps and industrial refrigeration units.

What models are compatible with the S1-031-09170-000?
This board fits a wide range of heat pump models from York, Coleman, and Luxaire, including the popular BP060E10P2AAA1, B3HP048A06, and 2TP04525458 series. Always verify the part number against your unit's data plate.

Can I use this board to replace a generic defrost timer?
No. As a dedicated OEM defrost control board, it is designed to interface with specific system sensors and safeties. Using a universal replacement may compromise efficiency or fail to trigger defrost cycles at the correct temperature intervals.

How do I know if the S1-031-09170-000 is the right part for my system?
Identify the part number directly from your existing board or the unit's parts list. This board is the official upgrade for legacy 031-09170-000 components.
