OEM Carrier Single-Pole Contactor 1-Pole 30 Amp 24V for Model PH15NA024000BAAA

This is the genuine OEM factory-replacement contactor for the Carrier PH15NA024000BAAA heat pump. The contactor is the high-voltage relay that bridges 240V line power to your compressor and condenser fan motor every time your thermostat calls for cooling or heating. When the contactor wears out — from pitted contacts, a burned coil, or welded poles — the system will fail to respond to the thermostat: the outdoor unit simply won't start, or it may run continuously without cycling off. Replacing this part with the correct OEM unit restores factory-spec switching performance and protects the compressor from premature wear caused by under-voltage or arcing at degraded contact points.

  • Specs: 1-Pole | 24 VAC coil voltage | 30 A FLA (Full Load Amps) | 150 A LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part# HN51KC024
  • OEM vs Generic: This is the genuine Carrier Factory Authorized Part, engineered to exact electrical tolerances for the PH15NA024000BAAA. Generic aftermarket contactors frequently ship with unverified contact ratings and coil resistance, increasing the risk of premature failure and voiding remaining equipment warranties.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Note that low-voltage (24V) coil leads may be positioned differently on the replacement unit — consult the unit wiring diagram on the inside of the access panel.
  • Warranty: 1-year OEM factory warranty. In-stock orders ship the same business day from our warehouse.

Compatibility: Engineered for the Carrier PH15NA024000BAAA heat pump. Verify the part number on your unit's wiring diagram or data plate before ordering. Cross-references include P282-0311, HN51CC024, P282-1304, and P282-1305. Have a question about fitment?

Frequently Asked Questions

Does this Contactor fit my Carrier PH15NA024000BAAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH15NA024000BAAA. 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 PH15NA024000BAAA?
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?
