OEM Carrier Single-Pole Contactor 1-Pole 24V 30A for Model PH15NB04800GBBAA

This is the factory OEM replacement contactor for the Carrier PH15NB04800GBBAA heat pump system. The contactor is a high-voltage relay that receives a 24-volt signal from the thermostat and closes to energize the compressor and condenser fan motor. When a contactor fails, the system will either refuse to start entirely, short-cycle unexpectedly, or — in the case of welded contacts — run continuously without shutting off. Pitted, burned, or stuck contacts are among the most common causes of a no-cool or no-heat service call.

  • Specs: 1-Pole (single-pole) | 24 VAC coil voltage | 30 amp FLA (Full Load Amps) | 150 amp LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part# HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact specifications for the PH15NB04800GBBAA. OEM contactors maintain proper coil resistance and contact ratings — generic units with loose tolerances can weld shut or drop prematurely under high compressor load.
  • Install difficulty: 2/5 — Always disconnect and lockout/tagout all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Verify 24V coil pull-in with a call from the thermostat after installation.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Confirmed fit for Carrier model PH15NB04800GBBAA. Also cross-references with alternate part numbers HN51CC024, P282-1304, P282-1305, P282-0311, 301362-101, and 301323-101.

Frequently Asked Questions

Does this Contactor fit my Carrier PH15NB04800GBBAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH15NB04800GBBAA. 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 PH15NB04800GBBAA?
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?
