OEM Carrier 2-Pole Contactor 30 Amp 24V (HN52KC025) for Model PY3PEA036090NB

This OEM 2-pole contactor is the factory-specified replacement for the Carrier PY3PEA036090NB condensing unit. The contactor acts as the primary high-voltage switching relay in your system — when the thermostat sends a 24V signal, the contactor closes to supply line-voltage power to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioner won't respond to a cooling call, hums without starting, or trips the breaker repeatedly. Burned, pitted, or welded contacts are telltale signs it's time for a replacement.

• Specs: 2-Pole (Double Pole) | 30 Amp FLA | 24V AC Coil | 50/60 Hz | Factory-matched Tyco Electronics design (OEM part series HN52KC025 / superseded by HN52KC024)
• OEM vs Generic: OEM contactors are built to exact Carrier contact gap, coil pull-in voltage, and arc-suppression tolerances. Aftermarket contactors frequently use lower-grade silver alloy contacts that pit and weld prematurely under compressor inrush current, risking compressor damage.
• Install difficulty: 2/5 — Disconnect all power and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Label L1/L2 (line) and T1/T2 (load) terminals carefully.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — order by 3PM local time.
