OEM Carrier Contactor 2-Pole 24V Coil HN52TC040 for Model GC024HSLNXET1XX1

This is the factory-specified OEM replacement contactor (part number HN52TC040) for the Carrier GC024HSLNXET1XX1 split-system condenser. 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 it fails, you may notice the outdoor unit completely failing to energize, the system humming without starting, or contacts that are visibly pitted, burned, or welded shut — all classic signs of a worn or failed contactor.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A contact rating | Direct OEM replacement for part number HN52TC040 | Factory-matched electrical specifications
  • OEM vs Generic: OEM contactors like this one are built to Carrier's exact coil pull-in voltage and contact material standards. Generic contactors frequently use lower-grade silver-alloy contacts that pit faster under load, leading to repeat failures within a single season.
  • Install difficulty: 3/5 — Always shut off power at both the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wire positions before removal. Verify line voltage has dropped to zero before touching any terminals.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: This contactor is the direct OEM replacement for the Carrier GC024HSLNXET1XX1 condenser unit. Always confirm the OEM part number HN52TC040 and coil voltage on your unit's wiring diagram or data plate before ordering. Not sure it fits?
