OEM Carrier 2-Pole Contactor (HN52KC025) for Model PY3PPA036090NB

This is the factory OEM replacement contactor for the Carrier PY3PPA036090NB split-system air conditioner. The contactor is the high-voltage relay that receives a 24V signal from the thermostat and closes the circuit to energize the compressor and condenser fan motor. When a contactor fails — due to pitted contacts, a burned coil, or contact welding — the result is typically a complete loss of cooling: the system hums, short-cycles, or won't start at all despite the thermostat calling for cooling.

• Specs: 2-Pole configuration | 24V AC coil voltage | Replaces OEM part number HN52KC025 | Factory-matched contact rating for the PY3PPA036090NB platform
• OEM vs Generic: This OEM contactor is manufactured to Carrier's exact contact gap, coil pull-in voltage, and current rating specifications. Generic contactors frequently use lower-grade contact materials that pit faster under load cycling, shortening service life and risking compressor damage.
• Install Difficulty: 2/5 — Always shut off power at both the disconnect and breaker before beginning. Tools needed: flat-head and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring before removal. Transfer line-voltage and low-voltage wires one at a time to the new contactor.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day when ordered before cutoff.
