OEM Carrier Contactor 2-Pole 24V Coil for Model PH13NR030000AFAA

This OEM contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Carrier PH13NR030000AFAA heat pump condensing unit. The contactor acts as the main electrical switch between the thermostat's 24V control signal and the high-voltage power supply to the compressor and condenser fan motor. When it fails, the most common symptoms include the outdoor unit not energizing at all, chattering or buzzing at the contactor, or the system staying locked off even with a valid call for cooling or heating.

  • Specs: 2-Pole configuration | 24V coil voltage | 30-amp rated contacts | Factory OEM tolerance — direct drop-in replacement for Carrier PH13NR030000AFAA
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contact tips rated for the exact amp draw of your Carrier system. Generic contactors often use lower-grade contacts that pit and arc more quickly, shortening service life and risking compressor damage.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or masking tape. Photograph all wiring before disconnecting. Swap one wire at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PH13NR030000AFAA heat pump condensing unit. Always verify coil voltage (24V) and pole configuration against your unit's wiring diagram and data plate before ordering. Our fitment team is available to confirm compatibility before you buy — reach out before placing your order.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR030000AFAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR030000AFAA. 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 PH13NR030000AFAA?
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.
