OEM Carrier 2-Pole Contactor 24V Coil for Model LC748LCCSRMY2600

This OEM replacement contactor is the factory-specified part for the Carrier LC748LCCSRMY2600 condensing unit. The contactor is the high-voltage relay that bridges your 24V control circuit signal to the 240V line voltage powering the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — your outdoor unit will either refuse to energize at all, run continuously without shutting off, or produce an audible buzzing without starting. Replaces OEM part numbers HN52TC024 and HN52TC040.

  • Specs: 2-Pole configuration | 24V control coil | 40A contact rating | 240VAC line voltage | Direct OEM factory replacement with exact terminal layout
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic aftermarket contactors often use lower-grade contact materials that pit and weld prematurely, leading to compressor run-on or hard-start failures within one to two seasons.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box AND the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wiring before disconnecting terminals. Capacitor discharge is recommended before working near the contactor.
  • Warranty: 1-year OEM factory warranty. Orders placed before our same-day shipping cutoff ship the same business day from our warehouse.

Compatibility: Designed for the Carrier LC748LCCSRMY2600 condensing unit. This listing covers both OEM part numbers HN52TC024 and HN52TC040 — verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's wiring diagram or data plate before ordering.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRMY2600?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRMY2600. 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 LC748LCCSRMY2600?
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?
