OEM Carrier 2-Pole Contactor HN51KC024 for Model HC1CJX048000ABAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier HC1CJX048000ABAA packaged or split-system unit. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to power the compressor and condenser fan motor. When a contactor fails — due to pitted contacts, a stuck plunger, or a burned coil — the outdoor unit will not energize even when the thermostat calls for cooling, resulting in warm air or a complete system lockout.

  • Specs: 2-pole configuration | 24V AC coil voltage | Rated for high-amperage compressor loads | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This OEM contactor uses factory-spec contact material and coil windings, ensuring proper pull-in voltage and long contact life. Generic contactors often use inferior contact alloys that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Swap wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model HC1CJX048000ABAA. Verify your existing contactor's pole count, coil voltage (24V), and amperage rating against your unit's data plate before ordering. Our fitment team is available to confirm compatibility — just reach out before you buy. In stock and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier HC1CJX048000ABAA?
Yes. This is the factory-specified OEM contactor for the Carrier HC1CJX048000ABAA. 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 HC1CJX048000ABAA?
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?
