OEM Carrier 2-Pole Contactor 24V Coil for Model C4850C50ZG030900

This is the factory-specified OEM replacement contactor (part number HN53CB115) for the Carrier C4850C50ZG030900 packaged unit. The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling, the contactor closes and supplies line voltage to the compressor and condenser fan motor. When the contactor fails, the most common symptoms are an AC system that won't turn on at all, a unit that hums but doesn't start, or visible pitting and burning on the contact points that cause intermittent operation or complete failure to energize.

• Specs: 2-pole configuration | 24V AC coil voltage | Rated for high-amperage compressor loads | Direct OEM replacement for part number HN53CB115 | Factory-matched contact material and coil resistance
• OEM vs Generic: OEM contactors use factory-grade contact alloys rated for the exact amperage draw of the C4850C50ZG030900 compressor. Generic contactors often use lower-grade contacts that pit faster under load, shortening replacement intervals significantly.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph existing wiring before removing any terminals. Transfer wires one at a time to avoid miswiring.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock units ship same business day from our warehouse.
