OEM Carrier Single-Pole Contactor 1-Pole 24V 30 Amp (HN51KC024) for Model PH16NC03000GBAAA

This is the factory OEM replacement contactor for the Carrier PH16NC03000GBAAA heat pump system. The contactor is the high-voltage relay that bridges your 24V control circuit to line voltage, energizing the compressor and condenser fan motor every time a cooling or heating call is made. When the contactor fails, the most common symptoms include the outdoor unit failing to start entirely, audible chattering or humming from the contactor coil, or the system running continuously because pitted contacts have welded themselves closed. Inspect contacts for burn marks, pitting, or carbon deposits — any of these are a clear sign it's time for a swap.

  • Specs: 1-Pole | 24 VAC Coil Voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz | OEM Part# HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact coil resistance and contact gap specifications for the PH16NC03000GBAAA. Aftermarket contactors may use lighter-gauge contacts prone to faster pitting and premature coil failure under high-cycle loads.
  • Install Difficulty: 2/5 — Shut off power at the disconnect and breaker before opening the unit. Photograph all wiring before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. 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.

Compatibility: Designed for Carrier model PH16NC03000GBAAA. Cross-references include P282-0311, HN51CC024, P282-1304, P282-1305, 72930DP1, and 72931DP1. Always confirm the OEM part number on your unit's wiring diagram or parts list before ordering. Have a fitment question?

Frequently Asked Questions

Does this Contactor fit my Carrier PH16NC03000GBAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH16NC03000GBAAA. 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 PH16NC03000GBAAA?
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?
