OEM Carrier Single-Pole Contactor 1P 30A 24V — HN51KC024 for Model PH3ANA048000BAAA

This is the genuine OEM factory-specified contactor for the Carrier PH3ANA048000BAAA packaged unit. The contactor is the primary high-voltage switching relay in your HVAC system — when the 24V thermostat signal energizes the coil, the contactor closes and delivers line voltage to the compressor and/or fan motor. A failed contactor typically presents as an AC unit that won't turn on at all, hums without starting, or runs continuously without cycling off due to welded contacts.

  • Specs: 1 Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC Coil | 50/60 Hz | 240/277V Line Voltage | Normally Open | OEM Part # HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact coil resistance and contact material specifications. Generic contactors often use inferior contact alloys prone to pitting and arcing, shortening compressor life and risking nuisance lockouts.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before disconnecting. Verify 24V coil pull-in after installation with a thermostat call for cooling.
  • Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH3ANA048000BAAA packaged units. The 048 designation indicates a 4-ton (48,000 BTU) system. Verify OEM part number HN51KC024 against your unit's wiring diagram or parts list before ordering. Not sure it fits?

Frequently Asked Questions

Does this Contactor fit my Carrier PH3ANA048000BAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH3ANA048000BAAA. 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 PH3ANA048000BAAA?
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?
