OEM Carrier Contactor HN51KC024 for Model HC1CJX030000AAAA Condenser

This OEM Carrier definite-purpose contactor (HN51KC024) is the direct replacement switch for your HC1CJX030000AAAA condensing unit. The contactor is the electrical relay that closes to send 240V power to the compressor and outdoor fan motor whenever the thermostat calls for cooling. Over years of cycling, the contacts pit, burn, or weld — causing no cooling, a unit that won't shut off, chattering, or a buzzing outdoor unit. This 1-pole, 24V coil, 30-amp contactor is matched to the HC1CJX030000AAAA's amperage and coil voltage for a precise, safe fit. It's one of the easier HVAC repairs: kill power, photograph and transfer the line, load, and coil wires one at a time, then mount. Replacing a worn contactor restores reliable starts and protects the compressor and capacitor from voltage stress. Genuine OEM construction means correct silver-alloy contacts and a coil rated for continuous duty. In stock and ships same-day when you order before 3PM CST. Our team can verify fitment if you have questions.

Frequently Asked Questions

Does this Contactor fit my Carrier Model HC1CJX030000AAAA Condenser?
Yes. This is the factory-specified OEM contactor for the Carrier Model HC1CJX030000AAAA Condenser. 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 HC1CJX030000AAAA Condenser?
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.
