OEM Carrier 1-Pole 30 Amp 24V Contactor HN51KC024 for Model PH13NB01900GAAAA

This OEM contactor is the factory-specified replacement for the Carrier PH13NB01900GAAAA heat pump condenser. The contactor is the high-voltage relay that connects and disconnects power to the compressor and/or condenser fan motor every time the thermostat calls for cooling or heating. When it fails — due to pitted or burned contacts, a stuck-open coil, or welded contact points — the system will either fail to start entirely, run continuously without shutting off, or short-cycle unpredictably. Replacing the contactor is one of the most common and cost-effective HVAC repairs you can perform.

  • Specs: 1-Pole | 24 VAC coil voltage | 30 Amp FLA | 150 Amp LRA | 50/60 Hz | OEM part number HN51KC024
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact factory tolerances for the PH13NB01900GAAAA. Generic aftermarket contactors may vary in contact gap, coil pull-in voltage, and silver alloy thickness — all of which affect service life under repeated switching loads.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Transfer wires one at a time to avoid mis-wiring the 24V coil leads.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PH13NB01900GAAAA heat pump condensers. Verify your unit's data plate lists part number HN51KC024 before ordering. Also cross-references: HN51CC024, P282-1304, P282-1305, 301362-101, 301323-101. Not sure it fits? Our HVAC parts specialists verify fitment before you buy — just ask.
