OEM Carrier Single-Pole Contactor 1-Pole 30A 24V — HN51KC024 for Model PH13NA04800GABAA

This OEM single-pole contactor (part# HN51KC024) is the factory-specified high-voltage switching relay for the Carrier PH13NA04800GABAA heat pump. The contactor acts as the primary electrical switch that allows 24V thermostat signals to close the high-voltage circuit to the compressor and condenser fan motor. When the contactor fails — through burned, pitted, or welded contacts — you'll experience symptoms ranging from the outdoor unit failing to energize on a call for cooling or heating, to the unit running continuously and refusing to shut off.

  • Specs: 1-Pole configuration | 30A full load amps (FLA) / 150A locked rotor amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM part number HN51KC024 | Cross-reference: 3100-15Q228, P282-0311
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, built to exact coil pull-in voltage and contact gap tolerances. Aftermarket contactors often use lower-grade silver-alloy contacts that pit faster under compressor inrush loads, dramatically shortening service life.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and electrical tape. Photograph all wiring before disconnecting. Verify 24V coil pull-in after installation with a thermostat call.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Factory-specified replacement contactor for Carrier PH13NA04800GABAA heat pump condensing units. Always verify the part number on your existing contactor's label and confirm against your unit's data plate before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NA04800GABAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NA04800GABAA. 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 PH13NA04800GABAA?
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?
