OEM Carrier 2-Pole 30 Amp 120V Contactor HN52KC052 for Model 09DE044800

This genuine OEM Carrier contactor (part# HN52KC052) is the factory-specified replacement for the Carrier 09DE044800 unit. The contactor acts as the high-voltage switching relay that connects and disconnects power to critical components — including the compressor and condenser fan motor — every time your system cycles. When the contactor begins to fail, you'll notice symptoms such as audible chattering or humming at the unit, the system refusing to start, or conversely, the AC running continuously and failing to shut off. In severe cases, burned or pitted contacts cause total system lockout.

• Specs: 2-Pole | 30 Amp (FLA) | 120V Coil | 50/60Hz | Definite Purpose Contactor | Factory-matched contact gap and spring tension
• OEM vs Generic: This is a genuine Carrier OEM part — not a universal substitute. OEM contactors meet exact coil pull-in voltage specs and contact material standards. Generic contactors can exhibit premature pitting, coil dropout under load, and shortened service life, risking compressor damage.
• Install Difficulty: 3/5 — High-voltage work requires disconnecting power at the disconnect box AND verifying zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse so your system is back up fast.
