OEM Carrier Single-Pole Contactor 30 Amp 24V — HN51KC024 for Model PH13NR01800GAEAA

This genuine OEM single-pole contactor (part number HN51KC024) is the factory-specified replacement for the Carrier PH13NR01800GAEAA heat pump condenser unit. The contactor acts as the primary high-voltage switching relay in the outdoor unit, energizing the compressor and condenser fan motor every time the thermostat calls for cooling or heating. When the 24V control circuit signals a call, the coil pulls in the contacts and closes the high-voltage circuit to the load. A failed contactor is one of the most common reasons an outdoor unit won't start — symptoms include the unit humming but not starting, chattering or buzzing sounds from the electrical panel, contacts welded shut causing the unit to run continuously, or a complete no-start condition.

  • Specs: 1-Pole configuration | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz rated | OEM part number HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact specifications for the PH13NR01800GAEAA. OEM contactors feature precision contact plating and coil windings calibrated to pull in reliably at 24V — off-brand units often chatter or fail to seat cleanly, risking compressor damage from voltage drop.
  • Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removing any terminals. Verify 24V coil pull-in after installation before closing the panel.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier model PH13NR01800GAEAA heat pump condenser. Verify your unit's wiring diagram and part list confirm HN51KC024 before ordering. Our fitment team is available to cross-reference your model and serial number — contact us before purchasing if unsure. Order now for same-day shipping.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR01800GAEAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR01800GAEAA. 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 PH13NR01800GAEAA?
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?
