OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200B511GA — HN51KC024

This is the factory OEM replacement contactor for the Carrier FIOP200B511GA packaged unit, matching OEM part number HN51KC024. The contactor is the high-voltage relay responsible for switching line-voltage power to the compressor and condenser fan motor whenever the thermostat calls for cooling. When it fails — whether due to burned contacts, a welded plunger, or a failed 24V coil — the result is an AC system that simply won't turn on, hums without starting, or runs continuously without cycling off.

  • Specs: 2-pole configuration | 24V AC coil | 30–40A contact rating | Direct OEM replacement per factory specification | Replaces Carrier part number HN51KC024
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contacts rated for the exact current draw of the FIOP200B511GA compressor. Generic contactors often use lower-grade contact materials that pit and arc faster, leading to premature failure and potential compressor damage.
  • Install difficulty: 3/5 — Always shut off power at the disconnect box and verify voltage is absent with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or camera for documenting connections. Coil wires and line/load lugs must be reconnected exactly as removed.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship the same business day from our stocked warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model FIOP200B511GA. Always verify pole count, coil voltage, and amperage rating on your unit's data plate before ordering. Our fitment team is available to confirm compatibility — contact us before you order if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200B511GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200B511GA — 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 FIOP200B511GA — 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.
