OEM Carrier 2-Pole Contactor 24V Coil for Model CA13NA06000GAAAA

This is the factory OEM replacement contactor (part number HN51JD026) for the Carrier CA13NA06000GAAAA split-system air conditioner. The contactor is a high-voltage relay controlled by the 24V thermostat signal — when the thermostat calls for cooling, the contactor closes to send 240V power to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an AC system won't respond to a cooling call, produces a loud chattering or buzzing from the outdoor unit, or runs continuously without shutting off when contacts weld together.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30–40A load rating | Replaces OEM part number HN51JD026 | Factory-matched contact gap and spring tension
  • OEM vs Generic: This OEM contactor uses factory-spec silver-alloy contact tips rated for thousands of switching cycles. Generic contactors frequently use lower-grade contacts that pit and weld prematurely, leading to compressor damage from continuous run conditions.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and wait 5 minutes before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Swap wires one at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed and factory-specified for the Carrier CA13NA06000GAAAA split-system condenser. Verify coil voltage (24V) and pole count on your existing contactor's label before ordering. Our HVAC parts specialists are available to confirm fitment — we verify compatibility before you buy. Order today and get same-day shipping on in-stock OEM parts.

Frequently Asked Questions

Does this Contactor fit my Carrier CA13NA06000GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier CA13NA06000GAAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier CA13NA06000GAAAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
