OEM Carrier Contactor 24V Coil 2-Pole for Model PH13NR024000ACAA

This is the factory OEM replacement contactor (part# HN51KC024) for the Carrier PH13NR024000ACAA heat pump / condenser unit. The contactor is the high-voltage switching relay that bridges 240V line power to your compressor and condenser fan motor every time your thermostat calls for cooling or heating. When a contactor fails — through pitted contacts, a burned coil, or a stuck plunger — the system will either fail to energize entirely, short-cycle, or trip the breaker repeatedly. Replacing a worn contactor is one of the most cost-effective repairs you can perform on a residential system.

  • Specs: 2-pole design | 24V AC control coil | Rated for 240V load circuit | Factory-matched contact material and gap tolerances for Carrier PH13NR024000ACAA
  • OEM vs Generic: OEM contactors use factory-grade silver-alloy contacts that resist pitting and arcing far longer than generic alternatives. Aftermarket units often use lower-grade contact surfaces that degrade faster under the high inrush current of a scroll compressor.
  • Install difficulty: 2/5 — Shut off power at both the disconnect and the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter to verify coil continuity. Always photograph existing wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed and verified for Carrier model PH13NR024000ACAA. Always confirm the coil voltage and pole configuration shown on your unit's data plate before ordering. Our HVAC parts specialists are available to verify fitment — contact us before you buy if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR024000ACAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR024000ACAA. 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 PH13NR024000ACAA?
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?
