OEM Carrier 1-Pole Contactor 25A 24V Coil for Model PY3PNA024060AB

This is the genuine OEM replacement contactor for the Carrier PY3PNA024060AB split-system air conditioner, factory part number HN51KB024. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to energize the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an AC unit that won't turn on at all, a compressor that hums but doesn't start, or contacts that are visibly burned, pitted, or welded shut — keeping the system energized even when cooling is not called for.

  • Specs: 1 Pole (Single Pole) | 24V AC Coil, 50/60 Hz | 25 FLA (Full Load Amps) | 35 RES | Direct OEM drop-in replacement for Carrier, Bryant, and Payne equipment
  • OEM vs Generic: The factory HN51KB024 contactor is manufactured to Carrier's exact contact gap, coil pull-in voltage, and current rating tolerances. Generic contactors frequently use lower-grade contact material that pits and welds faster under the high inrush current of a compressor start, leading to premature failure and potential compressor damage.
  • Install difficulty: 2/5 — Always shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting — thermostat (Y) wires attach to the coil terminals, and line/load wires must be re-landed correctly. Verify contacts are fully opening and closing after installation.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: This contactor is the direct OEM replacement for Carrier PY3PNA024060AB split-system condensers. Also used across a wide range of Carrier, Bryant, and Payne air conditioner and heat pump condensing units that specify a 1-pole, 24V coil, 25 FLA contactor. Always verify your existing contactor's pole count, coil voltage, and amp rating against your unit's wiring diagram before ordering. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy.

Frequently Asked Questions

Does this Contactor fit my Carrier PY3PNA024060AB?
Yes. This is the factory-specified OEM contactor for the Carrier PY3PNA024060AB. 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 PY3PNA024060AB?
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?
