OEM Carrier 2-Pole Contactor 24V Coil for Model HC1CJX048000AAAA

This is the factory OEM replacement contactor (part number HN51KC024) for the Carrier HC1CJX048000AAAA packaged or split-system unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to send line voltage to the compressor and condenser fan motor. When it fails — due to pitted contacts, a burned coil, or a contacts stuck open or closed — the system will either refuse to start, fail to cool, or run continuously without responding to thermostat commands.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact amperage rating | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This OEM contactor meets Carrier's exact coil sensitivity and contact rating specifications. Generic contactors may use lower-grade silver alloy contacts that pit faster under load, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and confirm voltage is absent with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed specifically for Carrier model HC1CJX048000AAAA. The "048" designation indicates a 4-ton capacity unit. Always verify the OEM part number on your existing contactor's label and cross-reference with HN51KC024 before ordering. If you have any fitment questions, our HVAC parts specialists are available to confirm compatibility before you buy — ensuring you get the right part the first time. In stock and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier HC1CJX048000AAAA?
Yes. This is the factory-specified OEM contactor for the Carrier HC1CJX048000AAAA. 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 HC1CJX048000AAAA?
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.
