The SOURCE1 2436138000 is a DPST normally open relay control designed for HVAC systems operating on 24VAC at 60Hz. This relay control is a direct OEM replacement part manufactured by SOURCE1, the genuine parts brand backed by York. HVAC technicians and service professionals rely on relay controls like this one to manage switching operations within heating, cooling, and air handling equipment. The 2436138000 is built to work with York, Johnson Controls, and related equipment lines where precision electrical switching is required.
A relay control in an HVAC system acts as an electrically operated switch. When the control board sends a 24VAC signal, the relay opens or closes a circuit to activate or deactivate components such as blower motors, compressors, condenser fans, and auxiliary heating elements. The DPST, or Double Pole Single Throw, configuration means this relay controls two separate circuits simultaneously with a single switching action. The normally open design means the relay circuit remains open until the coil is energized, which is a common and safe configuration in HVAC control systems.
Using a genuine OEM relay control like the SOURCE1 2436138000 ensures the replacement matches the original electrical specifications of the equipment. Aftermarket substitutes may not meet the same tolerance levels, which can lead to premature failure or inconsistent system performance. For field technicians completing a service call or contractors restocking their parts inventory, this relay control is a reliable, spec-matched solution for York and compatible systems. The part number S1-02436138000 is also associated with this component in York service documentation.
The SOURCE1 2436138000 relay control delivers reliable 24VAC DPST switching for York HVAC systems, providing a genuine OEM fit that helps restore proper system operation quickly and confidently.
