OEM Carrier 2-Pole Contactor 35A 208/240V for Model YAC36100YAC305A

This OEM replacement contactor (part number HN52KC053) is the factory-specified high-voltage switching relay for the Carrier YAC36100YAC305A condensing unit. The contactor acts as the primary electrical gatekeeper between your thermostat's 24V control signal and the high-voltage power supply to the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contact points, a worn coil, or mechanical sticking — the outdoor unit will fail to energize entirely, leaving you with a system that runs the air handler but produces no cooling whatsoever.

• Specs: 2-Pole | 35 Amps | 208/240V coil | OEM part number HN52KC053 | Factory-matched contact rating for Carrier YAC36100YAC305A
• OEM vs Generic: This is a genuine Carrier OEM contactor, manufactured to exact factory specifications. Generic contactors often use lower-grade contact materials that pit faster under load cycling, shortening service life significantly.

Photograph all wiring connections prior to removal.
• Warranty: 1-year OEM factory warranty. Orders ship same business day from our stocked warehouse — no waiting on special orders.
