OEM Carrier 2-Pole Contactor HN52TC040 for Model GC072CBRNXET1XX1

This is the factory OEM replacement contactor (part number HN52TC040) for the Carrier GC072CBRNXET1XX1 condensing unit. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to power the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a stuck plunger, or a burned coil — the outdoor unit will not respond when the thermostat calls for cooling, leaving you with warm air and a system that appears completely unresponsive.

  • Specs: 2-pole configuration | 24V AC coil voltage | Heavy-duty contacts rated for high-amperage compressor loads | Direct OEM replacement for part number HN52TC040
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact contact gap, coil pull-in voltage, and amperage rating. Aftermarket contactors frequently use lower-grade contact materials that pit and weld faster, leading to repeat failures and potential compressor damage.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: 1/4" and 5/16" nut drivers, flathead screwdriver, needle-nose pliers, multimeter. Photograph all high-voltage and low-voltage wire connections before removal. The 24V thermostat wires and line-voltage wires must be transferred exactly as wired on the original unit.
  • 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 GC072CBRNXET1XX1 condensing unit. Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Carrier GC072CBRNXET1XX1?
Yes. This is the factory-specified OEM contactor for the Carrier GC072CBRNXET1XX1. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier GC072CBRNXET1XX1?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
