OEM Carrier 2-Pole Contactor 24V Coil HN52TC040 for Model GC024CBRNDET1XX1

This is the factory OEM replacement contactor (part number HN52TC040) for the Carrier GC024CBRNDET1XX1 condensing unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When this component fails — whether due to pitted contacts, a burned coil, or a stuck plunger — the outdoor unit will not energize at all, even when the thermostat is calling for cooling. You may hear a click with no compressor start, or no response from the outdoor unit whatsoever.

• Specs: 2-pole configuration | 24V AC coil voltage | Matched to factory amperage rating | Direct OEM replacement for part number HN52TC040
• OEM vs Generic: OEM contactors use silver-alloy contact tips rated to factory specifications, providing consistent performance under high-cycle loads. Generic contactors often use lower-grade contact materials that pit faster, especially in high-humidity or high-duty-cycle environments.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify voltage is absent with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
