OEM Carrier 1-Pole 30 Amp Contactor HN51KC024 for Model PH13NR048000AHAA

This is the factory-specified OEM contactor for the Carrier PH13NR048000AHAA heat pump. The contactor is the high-voltage relay that receives a low-voltage (24V) signal from the thermostat or control board and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails, common symptoms include the unit failing to start, the compressor running continuously even when cooling isn't called for, audible chattering or humming from the electrical compartment, or visible pitting and burning on the contact faces. Replacing a worn contactor promptly prevents downstream damage to the compressor — one of the most expensive components in the system.

  • Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil Voltage | 50/60 Hz | OEM Part Number HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact coil impedance and contact silver-alloy specifications. Generic contactors frequently use thinner contact wafers and lower-grade coil windings that accelerate pitting and increase pull-in voltage variance — shortening compressor life.
  • Install Difficulty: 2/5 — Disconnect and lock out all power before opening the electrical compartment. Photograph all wiring before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Verify 24V coil pull-in after installation before restoring line voltage.
  • Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH13NR048000AHAA (4-ton R-410A single-stage heat pump). Always confirm the part number on your unit's wiring diagram or data plate before ordering. Need fitment help? Our HVAC parts specialists verify compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR048000AHAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR048000AHAA. 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 PH13NR048000AHAA?
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?
