OEM Carrier 2-Pole Contactor HN52TC040 for Model GC072HSLCXET1XX1

This is the factory OEM replacement contactor (part number HN52TC040) for the Carrier GC072HSLCXET1XX1 split-system unit. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the high-voltage circuit to power the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck armature, or a failed coil — your system will either not respond to a call for cooling at all, or will run continuously without shutting off. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs available.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for compressor and condenser fan loads | Direct OEM replacement, part number HN52TC040
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact rating specifications. Generic contactors may use lower-grade contact materials that pit faster under load, leading to premature failure and potential compressor damage.
  • Install Difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier GC072HSLCXET1XX1. Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. If you have any questions about fitment, our HVAC parts specialists can confirm compatibility before you buy. Order today and receive same-day shipping on all in-stock parts.

How do I replace the contactor on my Carrier OEM Carrier Contactor 2-Pole 24V Coil HN52TC040 — GC072HSLCXET1XX1?
Difficulty: Medium (30–45 min)

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.
