OEM Carrier 2-Pole Contactor 24V 40A (HN52PD024) for Model PH4RNG060000BBAA

This is the genuine OEM Carrier contactor (part number HN52PD024), the factory-specified replacement for the Carrier PH4RNG060000BBAA packaged unit. The contactor is a high-voltage relay that responds to your thermostat's 24V control signal to switch line-voltage power to the compressor and condenser fan. When a contactor fails, the most common symptoms include the outdoor unit failing to energize at all, the system humming without the compressor starting, or pitted/welded contacts that keep the unit running continuously even after a call for cooling ends.

• OEM vs Generic: Genuine Carrier OEM contactors use factory-spec contact alloys and coil windings, ensuring precise pull-in at 24V and rated contact life. Generic contactors may use softer contact materials that pit and fuse prematurely, especially on high-cycling residential systems.
