OEM Carrier Single-Pole Contactor 30 Amp 24V for Model PH15NB04200GBAAA

This is the genuine OEM factory-replacement contactor for the Carrier PH15NB04200GBAAA heat pump system. The contactor is the high-voltage relay that closes the power circuit to the compressor and condenser fan motor every time your thermostat sends a 24V call for cooling or heating. When the contactor fails — whether from pitted contacts, a burned coil, or welded-shut points — your system may hum without starting, fail to turn on entirely, or run continuously without responding to the thermostat. Part number HN51KC024 is the exact factory-specified replacement.

  • Specs: 1-Pole configuration | 30 Amps FLA / 150 Amps LRA | 24 VAC coil voltage | 50/60 Hz | Screw terminal connections | R-410A system compatible
  • OEM vs Generic: This OEM contactor is engineered to Carrier's exact specifications for pull-in voltage, contact gap, and arc suppression. Generic contactors often use lighter-gauge contacts that pit faster and coils wound to looser tolerances, shortening service life — especially in high-cycle residential heat pump applications.
  • Install difficulty: 2/5 — Always shut off power at the disconnect box and wait 5 minutes before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in after installation with the thermostat calling for a stage.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Verified fit for Carrier model PH15NB04200GBAAA. This contactor is also used across a broad range of Carrier, Bryant, and Payne residential and light-commercial HVAC equipment rated up to 5 tons (60,000 BTU). Always confirm the part number against your unit's wiring diagram or parts list before ordering. Our team is available to verify fitment — contact us before you buy if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier PH15NB04200GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH15NB04200GBAAA. 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 PH15NB04200GBAAA?
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?
