OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200B601GA — HN51KC024

This OEM contactor (part number HN51KC024) is the factory-specified high-voltage relay replacement for the Carrier FIOP200B601GA packaged unit. The contactor acts as the primary switching device that closes the high-voltage circuit to the compressor and condenser fan motor when the thermostat calls for cooling. A failed or worn contactor typically presents as an air conditioner that won't start despite the thermostat calling, audible chattering or buzzing at the contactor, pitted or burned contact points, or a system that runs continuously without cycling off.

  • Specs: 2-pole configuration | 24V AC coil voltage | Factory-matched amperage rating | Replaces OEM part number HN51KC024
  • OEM vs Generic: This is a genuine OEM Carrier contactor engineered to exact factory specifications. Generic contactors frequently feature substandard contact materials that pit and corrode faster, leading to premature failure and potential compressor damage — especially under high-load summer conditions.
  • Install difficulty: 3/5 — Always disconnect power at the disconnect box AND the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, insulated gloves. Photograph all wire connections before removal. Coil wires connect to the low-voltage terminals; line and load wires carry high voltage — label and handle accordingly.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed as a direct OEM replacement for the Carrier FIOP200B601GA packaged unit. Always verify your existing contactor's pole count, coil voltage, and amperage rating against your unit's data plate before ordering to ensure proper fitment. Our HVAC parts specialists are available to confirm compatibility before you purchase — order with confidence and get back up and running fast with same-day shipping.

Frequently Asked Questions

Does this Contactor fit my Carrier FIOP200B601GA — HN51KC024?
Yes. This is the factory-specified OEM contactor for the Carrier FIOP200B601GA — 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 FIOP200B601GA — 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.
