OEM Carrier 2-Pole Contactor 35A 208/240V for Model 09DE098C900

This OEM contactor (part number HN52KC053) is the factory-specified high-voltage relay for the Carrier 09DE098C900. The contactor acts as the main power switch between your disconnect and the compressor and condenser fan motor — when the thermostat calls for cooling, the 24V control board energizes the contactor coil, closing the high-voltage circuit and starting the outdoor unit. When a contactor fails, the most common symptom is an air conditioner that simply won't turn on despite the thermostat calling for cooling, or one that chatters, burns, or shows visible pitting on the contact points.

• Specs: 2-pole | 35 Amps | 208/240V load voltage | 24V coil | Replaces OEM part number HN52KC053
• OEM vs Generic: This is a genuine Carrier OEM contactor built to factory tolerance. Generic contactors may use lower-grade contact materials that arc and pit faster, reducing service life — especially in high-cycle cooling climates.
• Install difficulty: 2/5 — Always shut off power at the disconnect AND the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old contactor. Swap wires one at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
