OEM Carrier 2-Pole Contactor 24V Coil for Model LC748LCCSRMYX2501

This is the factory-specified OEM replacement contactor (part number HN52TC040) for the Carrier LC748LCCSRMYX2501 condensing unit. The contactor is a high-voltage relay that receives a 24V signal from your thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or a stuck plunger — your outdoor unit will fail to energize entirely, leaving your system blowing warm air despite the thermostat calling for cooling.

  • Specs: 2-pole configuration | 24V AC coil | Rated for R-410A system amperage draws | Direct OEM replacement for part number HN52TC040 | Factory-matched contact material for long service life
  • OEM vs Generic: The OEM HN52TC040 contactor uses factory-grade contact alloys and a precision-wound coil calibrated to Carrier's exact pull-in voltage. Generic contactors often use lower-grade contact materials that pit faster under load cycling, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all high-voltage wire connections before removing the old contactor and transfer one wire at a time to avoid miswiring.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Designed as a direct OEM drop-in replacement for the Carrier LC748LCCSRMYX2501 condensing unit using part number HN52TC040. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate prior to ordering. Our fitment team is available to confirm compatibility before you buy — fast shipping means you're back up and running today.

Frequently Asked Questions

Does this Contactor fit my Carrier LC748LCCSRMYX2501?
Yes. This is the factory-specified OEM contactor for the Carrier LC748LCCSRMYX2501. 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 LC748LCCSRMYX2501?
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.
