OEM Carrier 1-Pole Contactor 30 Amp 24V Coil — HN51KC024 for Model PH10JA03600GAGAA

This is the genuine OEM factory-authorized contactor for the Carrier PH10JA03600GAGAA packaged unit. The contactor is the high-voltage switching relay that closes when your thermostat sends a 24V call for cooling or heating, allowing line-voltage power to flow to the compressor and fan motor. When the contactor fails, symptoms include the system not responding to a thermostat call, the compressor not energizing, audible chattering or humming from the control box, or burned/pitted contact points that cause intermittent operation or total shutdown.

  • Specs: 1-Pole configuration | 30A Full Load Amps (FLA) / 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part #HN51KC024
  • OEM vs Generic: This Factory Authorized Part is engineered to meet exact Carrier specifications, ensuring proper coil pull-in voltage, contact gap tolerance, and terminal fitment. Generic contactors may use undersized contact material that pits and welds prematurely under high-cycle summer loads.
  • 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. Verify 24V coil energization after installation with a thermostat call.
  • Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Confirmed fit for Carrier model PH10JA03600GAGAA. Also used across a wide range of Carrier, Bryant, and Payne residential and light-commercial HVAC systems specifying a 1-pole, 30A, 24V contactor. Always verify your unit's wiring diagram and parts list before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier PH10JA03600GAGAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH10JA03600GAGAA. 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 PH10JA03600GAGAA?
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?
