OEM Carrier 2-Pole Contactor 24V Coil for Model LC748LCCSRLY2101

This OEM replacement contactor is the factory-specified part for the Carrier LC748LCCSRLY2101 condensing unit. The contactor acts as a high-voltage relay, receiving a 24V signal from the thermostat control circuit and switching line voltage to energize the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a stuck or burned coil, or worn contact tips — the most common symptoms are an air conditioner that won't turn on at all, a compressor that hums but won't start, or a unit that runs continuously without cycling off. OEM part numbers HN53CC024 and HN52TC040 are the factory-authorized replacements for this model.

  • Specs: 2-pole configuration | 24V AC coil | Factory-rated amperage for compressor and fan loads | Direct OEM replacement — no wiring modifications required
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic units frequently use lower-grade alloys that pit and weld shut prematurely, causing compressor failure or a unit stuck in the ON position — a costly secondary repair.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead 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. In-stock units ship same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered specifically for the Carrier LC748LCCSRLY2101 condensing unit. Cross-references OEM part numbers HN53CC024 and HN52TC040. Verify coil voltage and pole configuration against your unit's wiring diagram before ordering. Our fitment team is available to confirm compatibility — don't hesitate to reach out before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRLY2101?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRLY2101. 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 LC748LCCSRLY2101?
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?
