OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200C521GA (HN51KC024)

This is the factory OEM replacement contactor for the Carrier FIOP200C521GA packaged unit. The contactor is the high-voltage relay that receives a 24V signal from the thermostat or control board and closes the circuit to send line voltage to the compressor and condenser fan motor. When it fails — whether due to burned or pitted contacts, a stuck plunger, or a failed coil — the system will appear completely unresponsive or will hum without starting. Replacing a worn contactor is one of the most common and cost-effective repairs in the field.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched contact rating | OEM Part Number: HN51KC024
  • OEM vs Generic: This OEM contactor is manufactured to Carrier's exact specifications, ensuring proper coil pull-in voltage, contact gap, and current rating. Generic contactors may use lower-grade silver-alloy contacts that pit faster under load, leading to repeat failures within a single season.
  • 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 removing the old contactor and transfer one wire at a time to avoid miswiring.
  • Warranty: 1-year OEM factory warranty. Orders received by 3 PM local time ship the same business day from our warehouse.

Compatibility: Designed specifically for the Carrier FIOP200C521GA packaged unit. Always confirm the OEM part number HN51KC024 against your unit's data plate or existing contactor label before ordering. Our HVAC parts specialists are available to verify fitment — contact us before you buy if you have any questions. In-stock and ready to ship today.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200C521GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200C521GA — 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 FIOP200C521GA — 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.
