OEM Carrier Single-Pole Contactor 30 Amp 24V Coil — HN51KC024 for Model PH13NR04800GAHAA

This is the genuine OEM factory-specified contactor for the Carrier PH13NR04800GAHAA heat pump system. The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling or heating, the 24V coil energizes, closing the contacts and delivering line voltage to the compressor. When the contactor fails, you'll experience symptoms ranging from the unit humming but not starting, the system refusing to turn on at all, or in the case of welded contacts, the compressor running continuously even when no call for cooling is present.

  • Specs: 1-Pole | 30 Amp FLA / 150 Amp LRA | 24 VAC coil voltage | 50/60 Hz | OEM Part # HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to exact Carrier factory tolerances. Generic aftermarket contactors may use lower-grade contact materials that pit, arc, and weld together faster under high-cycle residential loads — leading to repeat failures within a single cooling season.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker panel before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before removing the old contactor. Verify coil pull-in with a 24V test call after installation.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Factory-specified replacement for Carrier model PH13NR04800GAHAA. Verify unit model and part number on the equipment data plate or original parts list prior to ordering. Our parts specialists are available to confirm fitment before you buy — don't hesitate to reach out. Order today for same-day shipping and get your system back up and running fast.

Frequently Asked Questions

Does this Contactor fit my Carrier PH13NR04800GAHAA?
Yes. This is the factory-specified OEM contactor for the Carrier PH13NR04800GAHAA. 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 PH13NR04800GAHAA?
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?
