OEM Carrier 2-Pole Contactor 24V Coil for Model LC748LCCSRMYX2600

This is the OEM factory-replacement contactor (part number HN52TC040) for the Carrier LC748LCCSRMYX2600 condensing unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and switches line voltage to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the outdoor unit will not energize even when the thermostat calls for cooling. You may hear the indoor air handler running but the outdoor unit remains completely off.

  • Specs: 2-pole configuration | 24V AC coil voltage | High-amperage contact rating | Factory-matched OEM part number HN52TC040 | Designed for R-410A residential condensing systems
  • OEM vs Generic: This is a genuine Carrier OEM contactor built to factory specifications. Generic contactors may use lower-grade contact materials that pit and weld more quickly under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always shut off power at both the disconnect and breaker before beginning. Tools needed: flat-head and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Transfer wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: This contactor is the factory-specified replacement for the Carrier LC748LCCSRMYX2600. Always verify coil voltage and pole configuration against your unit's wiring diagram and data plate before ordering. Our technical team is available to confirm fitment — reach out before you order if you have any questions. Order today and receive same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRMYX2600?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRMYX2600. 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 LC748LCCSRMYX2600?
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?
