OEM Carrier 2-Pole Contactor 30A 24V — HN52KC024 for Model 09BY024N611

This is the genuine OEM Carrier contactor (part number HN52KC024), the factory-specified replacement for Carrier model 09BY024N611 HVAC equipment. The contactor is a high-voltage switching relay that opens and closes the circuit to your compressor and condenser fan motor every time your thermostat calls for cooling. When the contactor fails, the most common symptom is an air conditioner that simply will not turn on — the thermostat calls, the control board responds, but nothing happens because the high-voltage circuit never closes. You may also notice visible pitting or burning on the contactor's contact points, a loud chattering or buzzing from the contactor coil, or the system short-cycling erratically.

• Specs: 2-Pole | 30 Amps | 24V Coil | 50/60 Hz rated | Definite purpose contactor | Factory OEM part number HN52KC024
• OEM vs Generic: This is a genuine Carrier OEM contactor, not an aftermarket substitute. OEM contactors are manufactured to exact coil pull-in voltage, contact gap, and amp rating specifications. Generic contactors often use lower-grade contact materials that pit and weld faster under high cycling loads, shortening equipment life.
• Install difficulty: 2/5 — Always shut off power at both the breaker and the disconnect box before starting. Photograph all wiring connections before removing the old contactor. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Verify the coil is de-energized before handling terminals.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
