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.
