OEM Carrier 2-Pole Contactor HN52TC040 for Model GC048HELNXET1XX1

This is the genuine OEM replacement contactor for the Carrier GC048HELNXET1XX1 packaged HVAC unit, factory part number HN52TC040. The contactor acts as the high-voltage relay that closes the circuit between your power supply and the compressor and condenser fan motor whenever the thermostat calls for cooling. When the contactor fails — due to pitted contacts, coil burnout, or a stuck plunger — the unit will appear completely unresponsive, hum without starting, or fail to energize despite the thermostat sending a 24V signal.

• Specs: 2-pole configuration | 24V AC coil voltage | Heavy-duty contact rating matched to factory specs | Direct OEM replacement for part number HN52TC040
• OEM vs Generic: This genuine Carrier contactor uses factory-specified contact materials and coil windings. Aftermarket contactors often use lower-grade silver-alloy contacts that pit faster under load, leading to premature failure — especially in high-cycle cooling climates.
• Install difficulty: 3/5 — Requires shutting off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a camera or phone to photograph existing wiring before removal. Transfer wires one at a time to avoid miswiring the high-voltage terminals.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.
