OEM Carrier 1-Pole Contactor 25A 24V Coil for Model PY3GNA036060NA (HN51KB024)

This is the genuine OEM replacement contactor for the Carrier PY3GNA036060NA condensing unit. The contactor is the high-voltage relay that closes the circuit to power your compressor and condenser fan motor every time the thermostat calls for cooling. When it fails, the most common symptoms are a completely unresponsive outdoor unit, a system that hums but won't start, or contacts that have welded shut — causing the compressor to run continuously even when the thermostat is satisfied.

  • Specs: 1 Pole (Single Pole) | 25 FLA (Full Load Amps) / 150 LRA (Locked Rotor Amps) | 24V AC Coil (50/60 Hz) | 240/277V line voltage | 1/4" quick-connect coil terminals | Normally open contacts
  • OEM vs Generic: This OEM Carrier contactor is factory-spec matched to the PY3GNA036060NA. Generic contactors may differ in terminal placement and contact material grade, increasing the risk of premature pitting, arcing, and early failure — especially during peak summer load cycles.
  • Install difficulty: 2/5 — Disconnect all power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, non-contact voltage tester. Always photograph existing wiring before disconnecting terminals. Swap wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PY3GNA036060NA. Also cross-references to Bryant and Payne units specifying part number HN51KB024. Always verify your unit's wiring diagram and data plate before ordering. Our HVAC parts specialists are available to confirm fitment — order with confidence and get your system back up and running today.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3GNA036060NA?
Yes. This is the factory-specified OEM contactor for the Carrier PY3GNA036060NA. 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 PY3GNA036060NA?
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?
