OEM Carrier 2-Pole Contactor HN52TC040 for Model GC024HSRNDET1XX1

This is the factory-specified OEM replacement contactor for the Carrier GC024HSRNDET1XX1 heat pump system. The contactor is the high-voltage relay responsible for switching power to the compressor and condenser fan motor when the thermostat signals a call for cooling or heating. When it fails, symptoms include an outdoor unit that won't energize, a system stuck in a continuous run condition, or visible pitting and burning on the contact points themselves. Replacing a worn contactor promptly protects your compressor — the most expensive component in the system.

• Specs: OEM Part Number HN52TC040 | 2-pole configuration | 24V coil voltage | Rated for high-amperage load switching | Factory-matched contact material and spring tension
• OEM vs Generic: This OEM contactor uses factory-grade contact alloy and coil windings calibrated for Carrier systems. Generic contactors often use lower-grade contact materials that pit faster under load, leading to premature failure and potential compressor damage.
• Install Difficulty: 3/5 — Disconnect and lock out power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and wire labels or tape. Photograph all wiring connections before removing the old unit. Always verify coil voltage with a multimeter before energizing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
