OEM Carrier 2-Pole 35A Contactor HN52KC053 for Model YAC42110YACX202AK

This is the genuine OEM replacement contactor for the Carrier YAC42110YACX202AK air conditioning system. The contactor is the high-voltage switching relay that energizes the compressor and condenser fan motor every time your thermostat calls for cooling. When the 24V control circuit energizes the coil, the contactor closes and delivers 208/240V power to the load side. A failed contactor is one of the most common causes of a completely unresponsive AC system — you may hear the indoor air handler running but the outdoor unit refuses to start, or the unit hums but does not cool.

• Specs: 2-Pole | 35 Amps | 208/240V load voltage | 24V coil voltage | OEM Part Number: HN52KC053
• OEM vs Generic: This is the factory-authorized Carrier OEM part, built to exact contact gap, coil pull-in voltage, and silver-alloy contact specifications. Generic contactors may use lower-grade contact alloys that pit and weld prematurely under heavy compressor load cycles.
• Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. Discharge capacitors before working near the contactor.
