OEM Carrier 2-Pole Contactor 24V Coil for Model CH13NA02500GABBA

This OEM contactor (part# HN51KC024) is the factory-specified replacement for the Carrier CH13NA02500GABBA split-system air conditioner. The contactor is a high-voltage relay that acts as the primary switch between your thermostat's 24V control signal and the high-voltage power supply to the compressor and condenser fan motor. When it fails, the most common symptoms include an outdoor unit that won't energize at all, a unit that runs continuously without shutting off, or visible pitting and burning on the contact points causing intermittent operation.

  • Specs: 2-pole configuration | 24V AC coil voltage | 30-amp rated contacts | Direct OEM replacement for part number HN51KC024 | Factory-matched coil pull-in and drop-out voltage tolerance
  • OEM vs Generic: This OEM contactor uses factory-spec contact material and coil windings, ensuring reliable pull-in at low 24V signal conditions. Generic contactors often use inferior contact alloys that pit and weld faster under load, leading to premature failure and compressor damage.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box and verify with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. High-voltage terminals must be fully seated and torqued on reassembly.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier CH13NA02500GABBA split-system condenser. Always verify coil voltage, pole count, and amperage rating against your unit's data plate before ordering. Our technical team is available to confirm fitment — reach out before you order if you have any questions. In stock and ships today.

Frequently Asked Questions

Does this Contactor fit my Carrier CH13NA02500GABBA?
Yes. This is the factory-specified OEM contactor for the Carrier CH13NA02500GABBA. 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 CH13NA02500GABBA?
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?
