OEM Carrier 2-Pole Contactor HN51JD026 for Model CA13NA06000GAABA

This OEM contactor (part# HN51JD026) is the factory-specified high-voltage relay for the Carrier CA13NA06000GAABA split-system air conditioner. The contactor acts as the primary power switch between your electrical panel and the compressor and condenser fan motor — when the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, closing the high-voltage contacts and allowing the system to run. A failed contactor is one of the most common reasons an AC unit won't start, hums without running, or trips a breaker. Burnt or pitted contacts are a telltale sign it's time to replace.

• Specs: 2-pole configuration | 24V coil voltage | Heavy-duty contacts rated for high-amperage load | Direct OEM replacement for part number HN51JD026
• OEM vs Generic: This factory OEM contactor meets Carrier's exact coil pull-in voltage and contact material specifications. Generic contactors often use inferior contact alloys that pit and arc more quickly, leading to premature failure and potential compressor damage.
• Install difficulty: 3/5 — Always shut off power at both the disconnect box and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or tape. Photograph all wiring connections before disconnecting. Verify power is off with a non-contact voltage tester before touching any terminals.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3PM ship same business day from our climate-controlled warehouse.

Compatibility: Designed specifically for the Carrier CA13NA06000GAABA 5-ton single-stage split-system condenser. Cross-reference your existing contactor's pole count and coil voltage rating against your unit's data plate before ordering to ensure correct fitment. Our HVAC parts specialists are available to verify compatibility before you buy — no guesswork required. In stock and ready to ship today.
