OEM Carrier 2-Pole Contactor 24V Coil for Model PH13NA048000ABAA

This OEM contactor (part number HN51KC024) is the factory-specified high-voltage switching relay for the Carrier PH13NA048000ABAA split-system heat pump condenser. The contactor acts as the primary power relay between the thermostat's 24V control signal and the high-voltage supply to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the condenser unit will either fail to turn on entirely, run continuously without cycling off, or produce a loud chattering or buzzing noise from the electrical panel area.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40 amp contact rating | Factory OEM replacement — exact fit for PH13NA048000ABAA
  • OEM vs Generic: This is a genuine Carrier OEM part sourced directly from the manufacturer. OEM contactors use silver-alloy contacts rated to factory spec, ensuring reliable switching life. Generic aftermarket contactors often use lower-grade contact materials that pit and fail prematurely under compressor inrush current.
  • Install Difficulty: 3/5 — This repair involves high-voltage wiring (240V). 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, needle-nose pliers, multimeter, and a camera or phone to photograph all wiring before removal. If you are not comfortable working with high-voltage circuits, consult a licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier PH13NA048000ABAA heat pump condenser. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate and wiring diagram before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NA048000ABAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NA048000ABAA. 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 PH13NA048000ABAA?
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?
