OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200B501GA — HN51KC024

This OEM contactor (part number HN51KC024) is the factory-specified replacement for the Carrier FIOP200B501GA packaged unit. The contactor is a high-voltage relay controlled by the 24V signal from your thermostat or control board. It closes to send line voltage to the compressor and condenser fan motor whenever a cooling call is made. When the contactor fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — the system will either refuse to start entirely, run continuously without cycling off, or produce a loud chattering or buzzing noise from the electrical panel.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage for FIOP200B501GA | OEM part number HN51KC024 | Direct drop-in replacement — no modifications required
  • OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory specifications. Generic contactors often use lower-grade contact materials that pit and corrode faster, especially in high-humidity or high-cycle environments — shortening system life and risking compressor damage.
  • Install difficulty: 2/5 — Shut off all power at both the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wire labels or tape. Always photograph existing wiring before disconnecting terminals. The contactor mounts with two screws and wires transfer directly terminal-for-terminal.
  • Warranty: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier FIOP200B501GA packaged unit. Verify coil voltage (24V) and pole count on your existing contactor's label before ordering. Our fitment team is available to confirm compatibility — just reach out before you buy. Order today and get same-day shipping on all in-stock OEM parts.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200B501GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200B501GA — 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 FIOP200B501GA — 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.
