OEM Carrier Contactor HN51KC024 for Model FIOP300B501GA

This OEM Carrier contactor is the heavy-duty switch that energizes your compressor and condenser fan motor on every call for cooling. A genuine factory replacement engineered for Carrier model FIOP300B501GA, it combines rated contacts with a 24V coil designed to endure repeated high-amperage switching without pitting, welding, or chatter. Burned or stuck contactor contacts are a frequent cause of systems that won't start, won't shut off, or buzz loudly at the outdoor unit—installing a fresh OEM contactor restores clean, dependable operation. Built to exact Carrier specifications, it ensures correct fit, proper terminal layout, and reliable coil pull-in for years of service. Installation is moderate for a trained technician, usually 20–30 minutes: disconnect power, photograph and transfer the line, load, and coil wires one at a time, and remount using the original screws. Professional installation is recommended for safety. All orders placed before 3PM CST ship same-day from our warehouse, letting you complete the repair quickly with a genuine part that performs and fits exactly like the original.

Frequently Asked Questions

Does this Contactor fit my Carrier Model FIOP300B501GA?
Yes. This is the factory-specified OEM contactor for the Carrier Model FIOP300B501GA. 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 Model FIOP300B501GA?
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.
