OEM Carrier Contactor 24V Coil 2-Pole for Model PH13NA042000ABAA

This is the factory-specified OEM replacement contactor for the Carrier PH13NA042000ABAA heat pump/air conditioning system. The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling or heating, the contactor closes to send line voltage to the compressor and condenser fan motor. A failed or pitted contactor is one of the most common reasons an outdoor unit won't power on, hums without starting, or shows signs of intermittent operation and tripped breakers.

• Specs: 2-Pole | 24V AC coil voltage | 30–40 amp rated | Factory-matched contact material and coil pull-in voltage for Carrier equipment
• OEM vs Generic: This OEM contactor (HN51KC024) uses factory-grade contact material rated to Carrier's exact switching cycles. Generic contactors often use lower-grade contacts that pit and oxidize faster, leading to repeat failures and potential compressor damage.
• Install difficulty: 2/5 — Always shut off power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdriver, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. Verify coil voltage and pole count match your unit's data plate.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
