OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — HN51KC024 for Model PH13NR01800GACAA

This is the genuine OEM Carrier contactor (part# HN51KC024) factory-specified for the Carrier PH13NR01800GACAA heat pump condenser. The contactor is the high-voltage switching relay that connects and disconnects line voltage to the compressor every time your thermostat calls for cooling or heating. When the contactor fails — through pitted or welded contacts, a burnt coil, or simply normal wear — the system will either refuse to start, hum without cooling, run continuously with no thermostat call, or trip a breaker. Replacing it promptly prevents compressor damage and restores reliable operation.

  • Specs: 1-Pole | 30A FLA / 150A LRA | 24 VAC Coil | 50/60 Hz | Factory OEM Part# HN51KC024
  • OEM vs Generic: OEM contactors are manufactured to Carrier's exact electrical and mechanical tolerances. Generic contactors may use lower-grade contact materials prone to faster pitting, arcing, and premature welding — especially under the high inrush loads of a heat pump compressor.
  • Install difficulty: 2/5 — Always disconnect and lock out all power before servicing. Photograph existing wiring before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, non-contact voltage tester. Verify 24V coil pull-in after installation with a thermostat call.
  • 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 PH13NR01800GACAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR01800GACAA. 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 PH13NR01800GACAA?
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?
