OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200E501GA — HN51KC024

This OEM replacement contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Carrier FIOP200E501GA packaged or split-system unit. The contactor acts as the primary switching relay that connects 240V line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. When it fails — due to pitted contacts, a burnt coil, or contact welding — the system will either refuse to start entirely, run continuously without cycling off, or trip the breaker repeatedly.

  • Specs: 2-Pole configuration | 24V AC control coil | 30–40A contact rating | Direct OEM replacement per factory specification | OEM Part No. HN51KC024
  • OEM vs Generic: This OEM contactor uses factory-grade silver-alloy contact tips rated for thousands of switching cycles. Generic contactors often use lower-grade contacts that pit or weld prematurely, leading to compressor damage and repeat service calls.
  • Install Difficulty: 3/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, and a multimeter. Photograph all wiring connections before removal. Coil wires are low-voltage (24V); line-side terminals carry 240V — exercise extreme caution.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our climate-controlled warehouse.

Compatibility: Engineered as a direct drop-in replacement for the Carrier FIOP200E501GA. Always verify pole count, coil voltage, and amperage rating on your unit's data plate or wiring diagram before ordering. Our HVAC parts specialists are available to confirm fitment — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200E501GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200E501GA — 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 FIOP200E501GA — 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?
