York 024-42455-000 Contactor

The York 024-42455-000 Contactor is a heavy-duty 3-pole HVAC contactor engineered for precise electrical circuit management in residential and commercial cooling systems. Rated for a 12A inductive load, this component is equipped with a 120V AC coil, making it a critical interface for switching power to compressors and condenser fan motors. As a technician, ensuring the correct inductive rating and coil voltage is paramount to prevent premature pitting or welded contacts during high-draw startup cycles. This unit serves as the direct replacement for York 024-31101-000, maintaining exact mounting footprints and terminal orientations to streamline field installation. The 3-pole configuration provides comprehensive phase control, ensuring balanced power distribution across the load. Whether you are performing a routine preventative maintenance swap or a reactive repair, this OEM York contactor ensures voltage-specific compatibility with existing control logic circuits, maintaining the operational integrity of the unit without requiring modification to the wiring harness or mounting bracket.

• Universal Compatibility: Serving as the direct replacement for York 024-31101-000, it eliminates the need for field modifications or drilling new mounting holes.
• Optimized Electrical Load: The 12 Amp rating is specifically calibrated for light commercial and standard residential compressors, reducing the risk of contact failure under load.
• High-Integrity 120V Coil: Built to withstand standard voltage fluctuations, the 120v coil ensures reliable armature engagement even during peak demand periods.
• Industrial-Grade 3-Pole Design: Provides robust switching for multi-phase or high-voltage single-phase applications, ensuring consistent power flow across all legs.

Is the York 024-42455-000 a direct swap for the 024-31101-000?
Yes, the 024-42455-000 is the manufacturer-designated updated part number and direct replacement. It matches the electrical specifications and physical dimensions of the legacy 024-31101-000 contactor.

Can I use a 24V coil contactor instead of this 120V model?
No. In HVACR systems, coil voltage must match the control circuit output. Using a different voltage (e.g., 24V) on a 120V circuit will cause immediate component failure. Always verify your transformer output before installation.

What are the signs that a York 12A contactor needs replacement?
Technicians should look for "chattering" (rapid clicking), burned or pitted contact points, or a burnt smell emanating from the coil. If the 120V coil tests for an open circuit with a multimeter, the contactor will fail to pull in, preventing the compressor from starting.
