OEM Carrier Single-Pole Contactor 1-Pole 30 Amp 24V for Model PH15NA024000BAAA

This is the genuine OEM factory-replacement contactor for the Carrier PH15NA024000BAAA heat pump. The contactor is the high-voltage relay that bridges 240V line power to your compressor and condenser fan motor every time your thermostat calls for cooling or heating. When the contactor wears out — from pitted contacts, a burned coil, or welded poles — the system will fail to respond to the thermostat: the outdoor unit simply won't start, or it may run continuously without cycling off. Replacing this part with the correct OEM unit restores factory-spec switching performance and protects the compressor from premature wear caused by under-voltage or arcing at degraded contact points.

• Specs: 1-Pole | 24 VAC coil voltage | 30 A FLA (Full Load Amps) | 150 A LRA (Locked Rotor Amps) | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is the genuine Carrier Factory Authorized Part, engineered to exact electrical tolerances for the PH15NA024000BAAA. Generic aftermarket contactors frequently ship with unverified contact ratings and coil resistance, increasing the risk of premature failure and voiding remaining equipment warranties.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removing the old contactor. Note that low-voltage (24V) coil leads may be positioned differently on the replacement unit — consult the unit wiring diagram on the inside of the access panel.
• Warranty: 1-year OEM factory warranty. In-stock orders ship the same business day from our warehouse.
