OEM Carrier 2-Pole Contactor 24V Coil for Model LC748LCCSRLY2501

This OEM replacement contactor is the factory-specified part for the Carrier LC748LCCSRLY2501 condensing unit. The contactor acts as a high-voltage relay controlled by the 24V signal from your thermostat — when the thermostat calls for cooling, the contactor closes 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 simply won't turn on, buzzes without starting, or runs continuously without shutting off. Replaces OEM part numbers HN53CC024 and HN52TC040.

  • Specs: 2-pole configuration | 24V coil voltage | Factory-rated amperage for compressor load | Direct OEM replacement for HN53CC024 / HN52TC040
  • OEM vs Generic: OEM contactors use factory-spec contact materials rated for the exact amperage draw of your Carrier LC748LCCSRLY2501 system. Generic contactors may use lower-grade contacts that pit and wear faster under high-cycling summer loads, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Label wires if needed for accurate reinstallation.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed by 3PM EST ship same business day from our climate-controlled parts warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier LC748LCCSRLY2501 condensing unit. Cross-references OEM part numbers HN53CC024 and HN52TC040. Always verify coil voltage and pole configuration against your unit's wiring diagram or data plate before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRLY2501?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRLY2501. 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 LC748LCCSRLY2501?
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?
