York s1-6555125 Furnace Control Board Kit 1 Stage

Product Description

The YORK s1-6555125 is an OEM integrated furnace control board kit designed for single-stage heating systems operating without a communication interface. Version 5.1 of this control board manages the sequencing of ignition, blower, and safety circuits within the furnace system. It serves as a direct replacement for the original board in compatible YORK equipment. Licensed HVAC technicians handle installation and replacement of this component during routine service, troubleshooting, or system restoration work. The kit format includes the necessary hardware to complete a proper board swap in the field.

This control board is intended for use in residential gas furnace applications where a single-stage heating configuration is employed and no communicating thermostat or communicating system interface is required. It fits into the furnace cabinet on the existing mounting points and connects to the low-voltage control wiring, ignition circuit, inducer, and blower motor. YORK equipment requiring VER5.1 board replacement represents the primary application for this part.
