What amp contactor do I need for my Carrier system?

The correct replacement for Carrier model PH13NA01800GABAA is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number PH13NA01800GABAA.

My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Single-Pole Contactor 1-Pole 30A 24V Coil — HN51KC024 for Model PH13NA01800GABAA

This is the genuine OEM Carrier contactor (part# HN51KC024), factory-specified for the Carrier PH13NA01800GABAA heat pump condensing unit. The contactor is the primary high-voltage switching relay in your outdoor unit — when the 24V thermostat signal calls for cooling or heating, the contactor coil energizes and closes the power circuit to the compressor and condenser fan motor. A failed contactor is one of the most common causes of an AC or heat pump that won't start, hums without running, chatters repeatedly, or — when contacts weld shut — runs continuously and won't shut off.

Specs: 1-Pole (single-pole) | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | Factory part# HN51KC024
OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact contact gap, coil pull-in voltage, and arc-suppression specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under compressor inrush loads, shortening service life significantly.
Install difficulty: 2/5 — Shut off power at the disconnect and verify zero voltage with a multimeter before touching any wiring. Photograph all wire connections before removal. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, multimeter. Swap wires one at a time to avoid miswiring the 24V coil leads.
Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NA01800GABAA heat pump condensing unit. Cross-references include P282-0311, HN51CC024, 301362-101, and 301323-101. Always verify your unit's data plate and wiring diagram before ordering — questions? Our parts team confirms fitment before you buy.
