OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200C621GA — HN51KC024

This is the genuine OEM replacement contactor for the Carrier FIOP200C621GA packaged unit, sold under OEM part number HN51KC024. The contactor is the high-voltage relay responsible for switching power to the compressor and condenser fan motor when the thermostat calls for cooling. When the contactor fails — due to burned or pitted contacts, a stuck plunger, or a failed coil — the result is an air conditioning system that simply won't energize, or one that runs continuously without cycling off. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs available.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for Carrier FIOP200C621GA | Direct OEM replacement for part number HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact coil pull-in voltage and contact material specifications. Generic contactors may use inferior contact alloys that pit and fail faster under high-cycle residential or light-commercial loads.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered as a direct drop-in replacement for the Carrier FIOP200C621GA packaged unit. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200C621GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200C621GA — 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 FIOP200C621GA — 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.
How fast does National HVAC Parts ship?
