OEM Carrier 1-Pole Contactor 24V 25 Amp HN51KB024 for Model PY3PNA024060NA

This is the genuine OEM replacement contactor for the Carrier PY3PNA024060NA condensing unit. The contactor is the high-voltage relay at the heart of your air conditioning system — when the thermostat sends a 24V signal, the contactor closes its contacts to deliver line-voltage power to the compressor and/or condenser fan motor. When the contactor fails, common symptoms include the outdoor unit failing to start entirely, a persistent buzzing or chattering from the electrical compartment, or welded contacts that leave the compressor running non-stop even with the thermostat off.

  • Specs: 1-Pole configuration | 24V 50/60Hz coil voltage | 25 FLA (Full Load Amps) | OEM part number HN51KB024 | Factory-matched replacement
  • OEM vs Generic: This is the genuine Carrier OEM contactor — not an aftermarket substitute. OEM contactors are manufactured to exact coil resistance and contact-surface specifications, ensuring reliable pull-in voltage and longer contact life compared to generic alternatives that may use undersized copper contacts.
  • Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker panel before opening the electrical compartment. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before removing any terminals from the old contactor.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY3PNA024060NA condensing unit. Verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our team is available to confirm fitment — contact us before you buy if you have any questions. In stock and ships today.

How do I replace the contactor on my Carrier OEM Carrier Contactor 1-Pole 24V 25A HN51KB024 — PY3PNA024060NA?
Difficulty: Medium (30–45 min)

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.
