OEM Carrier 2-Pole Contactor for Model LC748LCCSRLY2601

This is the OEM-specified replacement contactor for the Carrier LC748LCCSRLY2601 condensing unit. The contactor is the high-voltage switching relay that receives a 24V signal from your thermostat and closes the circuit to send line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, coil burnout, or contact welding — the most common symptoms are an air conditioner that won't turn on at all, a unit that runs continuously without shutting off, or visible arcing and burning inside the electrical compartment. OEM part numbers for this application are HN53CC024 and HN52TC040.

  • Specs: 2-pole configuration | 24V AC coil voltage | 40A contact rating | Direct factory-matched replacement for Carrier LC748LCCSRLY2601 | OEM part numbers HN53CC024 and HN52TC040
  • OEM vs Generic: OEM contactors use silver-alloy contact tips rated for thousands of switching cycles. Generic alternatives often use lower-grade alloys that pit faster under load, increasing the risk of welded contacts and compressor damage.
  • Install Difficulty: 2/5 — Turn off power at both the disconnect and the breaker before opening the electrical compartment. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil continuity and contact resistance. Photograph all wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed as a direct OEM replacement for the Carrier LC748LCCSRLY2601 condensing unit. Cross-reference your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. If you need fitment confirmation, our HVAC parts specialists are available to verify compatibility before you buy. Order today and get back to cool — fast.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRLY2601?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRLY2601. 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 LC748LCCSRLY2601?
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?
