OEM Carrier 2-Pole Contactor 24V Coil for Model PH10JA024000AGAA

This is the factory OEM replacement contactor for the Carrier PH10JA024000AGAA heat pump system. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When a contactor fails — due to worn or pitted contact points, a burned coil, or contacts welded shut — your system will either fail to start entirely, run continuously without shutting off, or produce a loud chattering or buzzing from the electrical cabinet.

  • Specs: 2-Pole design | 24V AC coil voltage | Factory-matched contact rating | OEM Part Number: HN51KB024
  • OEM vs Generic: This is the exact OEM contactor specified by Carrier for the PH10JA024000AGAA. OEM contacts use higher-grade silver alloy that resists pitting and arcing far longer than generic alternatives, protecting your compressor investment.
  • Install Difficulty: 3/5 — Line voltage (240V) is present inside the disconnect and unit cabinet. Always shut off power at the disconnect box AND the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH10JA024000AGAA. Always verify coil voltage and pole configuration against your unit's wiring diagram or data plate before ordering. Our fitment specialists are available to confirm compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier PH10JA024000AGAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH10JA024000AGAA. 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 PH10JA024000AGAA?
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.
