OEM Carrier 2-Pole Contactor 24V Coil for Model C48A402761 (HN53CB115)

This is the factory-specified OEM contactor for the Carrier C48A402761 packaged unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat or control board and closes the circuit to energize the compressor and condenser fan motor. When a contactor fails, the most common symptoms include the outdoor unit failing to start entirely, intermittent operation, audible chattering or buzzing at the contactor, or visible pitting and burning on the contact points. Replacing a worn contactor promptly protects the compressor from voltage irregularities and premature failure.

  • Specs: 2-Pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier C48A402761 packaged equipment | OEM part number HN53CB115
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact contact material and spring-tension specifications. Generic contactors often use lower-grade silver-alloy contacts that pit faster under load cycling, leading to repeat failures within one to two seasons.
  • Install difficulty: 3/5 — Always shut off power at the disconnect and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Photograph all wiring connections before removing the old contactor to ensure correct reassembly.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier C48A402761 packaged unit. Always confirm coil voltage and pole configuration match your unit's wiring diagram before installation. Our HVAC parts specialists are available to verify fitment prior to your order — don't hesitate to reach out. In stock and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier C48A402761 (HN53CB115)?
Yes. This is the factory-specified OEM contactor for the Carrier C48A402761 (HN53CB115). 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 C48A402761 (HN53CB115)?
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?
