OEM Carrier 2-Pole Contactor 24V Coil for Model PY4GNAA30060AA

This is the factory OEM replacement contactor for the Carrier PY4GNAA30060AA split-system air conditioner, sold under OEM part number HN51KC024. The contactor is the high-voltage relay responsible for switching power to your compressor and condenser fan motor every time the thermostat calls for cooling. When it fails — due to worn contacts, pitting, or a burned coil — the outdoor unit will not energize even though the indoor air handler continues to run, leaving you with warm air and a frustrated household.

  • Specs: 2-Pole configuration | 24V AC coil voltage | Factory-rated contact amperage | Direct OEM replacement — no modifications required
  • OEM vs Generic: OEM contactors (HN51KC024) use factory-spec silver-alloy contact tips rated for thousands of switching cycles. Generic contactors often use inferior contact materials that pit and weld prematurely, shortening compressor life and increasing service callbacks.
  • Install difficulty: 2/5 — Always disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. The contactor slides into the control panel bracket and terminals are screw-type for straightforward replacement.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY4GNAA30060AA packaged or split-system unit. Confirm your unit's data plate matches the 24V coil specification and 2-pole configuration before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before your order ships — call or chat with us today.

Frequently Asked Questions

Does this Contactor fit my Carrier PY4GNAA30060AA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier PY4GNAA30060AA — HN51KC024. 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 PY4GNAA30060AA — HN51KC024?
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?
