OEM Carrier Contactor 2-Pole 24V Coil for Model LC748LCCSRLP2500

This is the factory OEM replacement contactor for the Carrier LC748LCCSRLP2500 condensing unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to deliver 240V power to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the air conditioner will not respond to a call for cooling, or it may run continuously without cycling off. OEM part numbers HN53CC024 and HN52TC040 are the factory-specified replacements for this model.

  • Specs: 2-pole configuration | 24V AC coil voltage | Rated for high-cycle residential and light-commercial duty | Replaces OEM part numbers HN53CC024 and HN52TC040
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for full amperage draw at startup. Generic contactors often use lower-grade contacts that pit and weld faster under compressor inrush current, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always shut off power at the disconnect box AND the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Discharge any capacitors in the cabinet before reaching in.
  • 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: Engineered specifically for the Carrier LC748LCCSRLP2500 condensing unit. Cross-references OEM part numbers HN53CC024 and HN52TC040. Confirm coil voltage (24V) and pole count on your existing contactor label before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before every order — contact us and we'll confirm compatibility at no charge.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRLP2500?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRLP2500. 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 LC748LCCSRLP2500?
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?
