OEM Carrier Contactor 2-Pole 24V Coil for Model GC048HELCXET1XX1

This is the factory OEM replacement contactor (part number HN52TC040) for the Carrier GC048HELCXET1XX1 packaged unit. The contactor is a high-voltage relay controlled by the 24V thermostat signal. When the thermostat calls for cooling, the contactor closes its contacts to send line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an air conditioner that won't start — symptoms include a system that clicks but doesn't run, pitted or burned contact points, or a contactor that sticks in the open or closed position, causing the unit to run continuously or not at all.

• Specs: 2-pole configuration | 24V AC coil voltage | 40-amp rated contacts | Direct OEM replacement for part number HN52TC040 | Factory-spec contact gap and coil pull-in voltage
• OEM vs Generic: OEM contactors feature factory-calibrated coil pull-in voltage and silver-alloy contact points rated for the full load amperage of your Carrier unit. Generic contactors may use lower-grade contact materials that pit and burn faster, leading to premature failure and potential compressor damage.
• Install Difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Line-voltage terminals must be torqued to spec to prevent arcing.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier GC048HELCXET1XX1 packaged unit (4-ton class). Always verify your existing contactor's pole count, amperage rating, and coil voltage against the data plate inside your unit before ordering. Our fitment team is available to confirm compatibility before you buy — same-day shipping ensures you're back up and running fast.
