OEM Carrier 2-Pole Contactor 35A 208/240V for Model 09DE146C900

This OEM contactor (part number HN52KC053) is the factory-specified high-voltage relay for the Carrier 09DE146C900. The contactor is the critical switching component that receives a 24V signal from the thermostat and closes to deliver line-voltage power to the compressor and condenser fan motor. When the contactor fails, the most common symptoms include an air conditioner that refuses to turn on, a system that hums but never starts, or pitted/burned contacts causing intermittent operation or complete failure to energize the outdoor unit.

• Specs: 35 Amps | 2-Pole | 208/240V coil voltage | Factory OEM part number HN52KC053 | Weight: 0.63 lbs
• OEM vs Generic: This is the genuine Carrier OEM contactor built to exact factory contact-gap, spring tension, and coil pull-in tolerances. Generic contactors often use lower-grade silver-alloy contacts that pit faster under compressor inrush currents, reducing service life significantly.
• Install difficulty: 3/5 — Requires shutting off power at the disconnect and breaker before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter to confirm de-energization. Always photograph all wiring connections before removal. Verify coil voltage matches your control circuit before installation.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
