OEM Carrier Contactor 24V 2-Pole for Model PY3PNA030060NA

This is the OEM factory-specified contactor for the Carrier PY3PNA030060NA packaged unit system. The contactor is a high-voltage relay that receives a low-voltage (24V) signal from your thermostat to close its contacts and deliver line voltage to the compressor and condenser fan motor. When this part fails, you'll typically experience an AC system that won't turn on at all, a compressor that hums but won't start, or visible pitting and burning on the contact surfaces — a telltale sign of contactor wear that demands immediate replacement.

• Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact amperage rating | Direct OEM replacement part number HN51KB024
• OEM vs Generic: This OEM contactor is manufactured to exact Carrier factory specifications, including precise coil resistance and contact surface alloy. Generic contactors often use lower-grade contact materials that pit and weld faster under the high inrush current of a compressor start, leading to premature failure.
• Install difficulty: 3/5 — Always disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Verify coil voltage and pole count match your existing unit data plate.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse when ordered before 3 PM.

Compatibility: Engineered specifically for the Carrier PY3PNA030060NA packaged unit. Always cross-reference the part number printed on your existing contactor and confirm coil voltage on your unit's data plate prior to ordering.
