OEM Carrier Single-Pole Contactor 30 Amp 24V — HN51KC024 for Model PH13NB042000AAAA

This is the genuine OEM factory-authorized replacement contactor for the Carrier PH13NB042000AAAA heat pump. The contactor is a high-voltage relay that engages the compressor and condenser fan circuit every time your thermostat sends a 24V cooling or heating call. Over time, contacts pit and burn from repeated arcing, or the coil can open entirely — resulting in an outdoor unit that simply won't energize. Common failure symptoms include the system not turning on at all, the compressor humming briefly then cutting out, or visible burn marks and pitting on the contact faces.

  • Specs: 1-Pole | 24 VAC coil voltage | 30 Amp FLA / 150 Amp LRA | 50/60 Hz | OEM part number HN51KC024
  • OEM vs Generic: Factory-authorized OEM contactors are built to exact Carrier tolerances with silver-alloy contact tips rated for the precise amp draw of your PH13NB042000AAAA compressor. Generic contactors often use inferior contact material that pits faster, shortening compressor life and risking nuisance lockouts.
  • Install difficulty: 2/5 — Shut off all power to the unit and discharge any stored capacitor charge before opening the electrical compartment. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter. Always photograph all wiring connections before disconnecting the old contactor. Verify 24V coil pull-in after installation with a call from the thermostat.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NB042000AAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NB042000AAAA. 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 PH13NB042000AAAA?
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?
