OEM Carrier Single-Pole Contactor 30A 24V Coil for Model PH16NA02400GBAAA

This is the factory OEM replacement contactor for the Carrier PH16NA02400GBAAA heat pump system. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to energize the compressor. When it fails — whether from pitted or burned contacts, a stuck open coil, or welded contacts — your outdoor unit will either refuse to start, run continuously without cycling off, or trip the breaker entirely. Replacing the contactor is one of the most common and cost-effective HVAC repairs a homeowner or technician can perform.

  • Specs: 1-Pole configuration | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24V AC coil voltage | 50/60 Hz | OEM Part# HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact factory specifications for the PH16NA02400GBAAA. Generic contactors may deviate in contact gap, coil pull-in voltage, and contact plating — leading to premature failure or nuisance trips.
  • Install difficulty: 2/5 — Shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter for coil continuity check. Always photograph all wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PH16NA02400GBAAA. This single-pole contactor is also commonly used across Carrier, Bryant, and Payne residential and light-commercial air conditioning and heat pump systems up to 5 tons (60,000 BTU). Verify your existing contactor's pole count, amperage, and coil voltage against your unit's data plate before ordering. Have a fitment question? Our team confirms compatibility before you buy — just reach out.

Frequently Asked Questions

Does this Contactor fit my Carrier PH16NA02400GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH16NA02400GBAAA. 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 PH16NA02400GBAAA?
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?
