OEM Carrier 2-Pole Contactor 24V Coil for Model LC748LCCSRLP2600

This is the factory-specified OEM contactor replacement for the Carrier LC748LCCSRLP2600 condensing unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an AC system that won't energize at all, a unit that hums but never starts, or visible pitting and burning on the contact points inside the unit. Replaces OEM part numbers HN53CC024 and HN52TC040.

  • Specs: 2-Pole configuration | 24V coil voltage | Factory-rated amperage for Carrier condensing applications | Direct OEM replacement — no modification required
  • OEM vs Generic: OEM contactors use factory-spec silver-alloy contact points rated for the exact load cycles of your Carrier unit. Generic contactors often use lower-grade contacts that pit faster under high-inrush compressor loads, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Line-voltage terminals must be torqued to spec to prevent arcing.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered as a direct fit for the Carrier LC748LCCSRLP2600 condensing unit. Cross-references OEM part numbers HN53CC024 and HN52TC040. Verify coil voltage and pole configuration on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — just ask.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRLP2600?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRLP2600. 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 LC748LCCSRLP2600?
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?
