OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200F621GA — HN51KC024

This is the factory OEM replacement contactor for the Carrier FIOP200F621GA packaged or split-system unit. The contactor is a high-voltage relay that receives a 24V signal from the thermostat or control board and closes to send line voltage to the compressor and condenser fan motor. When the contactor fails — whether due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will not cool. Symptoms include an AC unit that hums but won't start, trips the breaker repeatedly, or simply does nothing when the thermostat calls for cooling.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier FIOP200F621GA | OEM part number HN51KC024 | Direct drop-in replacement with no modification required
  • OEM vs Generic: This factory OEM contactor uses silver-alloy contact tips rated to exact Carrier specifications, ensuring proper arc suppression and contact closure life. Generic contactors often use lower-grade contact materials that pit and weld prematurely, causing nuisance lockouts or compressor damage.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdriver, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all high-voltage wiring before disconnecting. Verify coil voltage and pole count match your existing unit data plate.
  • Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our climate-controlled warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier FIOP200F621GA. Always cross-reference the OEM part number HN51KC024 and confirm pole count and coil voltage against your unit's data plate before ordering. Our HVAC parts specialists are available to verify fitment — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200F621GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200F621GA — HN51KC024. 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 FIOP200F621GA — HN51KC024?
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.
