OEM Carrier 2-Pole Contactor 24V Coil for Model CH13NA03100GABBA

This is the factory OEM replacement contactor for the Carrier CH13NA03100GABBA split-system air conditioner, sold under OEM part number HN51KC024. The contactor is the primary high-voltage switching relay in your condensing unit — when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the contacts and supplying line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an air conditioner won't start, hums continuously, or runs erratically. Pitted or burned contacts, a weak coil, or contacts that weld shut are all telltale signs it's time for a replacement.

• Specs: 2-pole design | 24V AC coil voltage | 30–40A contact rating | Direct OEM replacement | Part number HN51KC024
• OEM vs Generic: This factory OEM contactor uses silver-alloy contacts rated to Carrier's exact load specifications. Generic contactors often use lower-grade contact materials that pit faster under high-cycle summer loads, leading to premature failure and potential compressor damage.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph all wiring connections before removing the old contactor. Line and load wiring must be transferred exactly as found.
• Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier CH13NA03100GABBA condensing unit. Always confirm coil voltage and pole configuration on your unit's data plate or wiring diagram before ordering.
