OEM Carrier 2-Pole Contactor 24V Coil HN51KC024 for Model CH16NA03600GBAAA

This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Carrier CH16NA03600GBAAA split-system condenser. The contactor acts as the high-voltage relay that connects line-voltage power to the compressor and condenser fan motor whenever the thermostat sends a 24V signal. When it fails, the most common symptoms include an air conditioner that won't turn on at all, a compressor that hums without starting, or a unit that runs continuously without shutting off due to welded contacts.

• Specs: 2-pole configuration | 24V AC coil voltage | Rated for Carrier CH16NA03600GBAAA 3-ton split-system condenser | Factory-matched contact rating for reliable high-voltage switching
• OEM vs Generic: This OEM unit is built to exact Carrier factory specifications, ensuring proper coil pull-in voltage and contact durability. Generic contactors often use lower-grade contact materials that pit and weld prematurely, leading to repeat failures within one to two seasons.
• Install difficulty: 3/5 — Requires shutting off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil continuity. Photograph all wiring connections before disconnecting the old contactor to ensure correct reinstallation.
