OEM Carrier 2-Pole Contactor HN52TC040 for Model GC024CBLCXET1XX1

This is the factory-specified OEM replacement contactor (part number HN52TC040) for the Carrier GC024CBLCXET1XX1 condensing unit. The contactor is a high-voltage relay that acts as the primary switching device in your outdoor unit — when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the high-voltage contacts and sending power to the compressor and condenser fan motor. A failed contactor is one of the most common causes of a completely unresponsive outdoor unit. Symptoms include the system not turning on at all, the compressor chattering or clicking without starting, or visible pitting and burning on the contact points themselves.

• Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact rating | Direct OEM replacement for part number HN52TC040
• OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact material specifications. Generic contactors frequently use lower-grade contact alloys that pit faster under load, leading to repeat failures — especially in high-cycle summer operation.
• Install Difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is absent with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring connections before removing the old unit. Transfer wires one at a time to avoid miswiring.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Designed as a direct drop-in replacement for the Carrier GC024CBLCXET1XX1 condensing unit. Always confirm your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering to ensure a proper fit. Our HVAC parts specialists are available to confirm compatibility before you buy — no guesswork required.
