OEM Carrier Contactor HC51KE024 for Model CH13NA02400GAAAA

This genuine OEM Carrier contactor (HC51KE024) is the heavy-duty switch that energizes the compressor and condenser fan in your CH13NA02400GAAAA every time the thermostat calls for cooling. The coil pulls the contacts closed to deliver line voltage; over time the contacts pit and burn, producing buzzing, hard starts, intermittent cooling, or a dead unit. Built to factory specifications, this contactor matches the original coil voltage, pole count, and amperage rating for a precise, drop-in replacement with no rewiring or adapters. It's one of the simplest HVAC repairs — shut off power at the disconnect, photograph the existing wires, transfer them to the matching terminals, and secure the new contactor, usually 20-30 minutes start to finish. Electrical work should always be handled by a licensed technician. Orders placed before 3PM CST ship same-day, so the fix moves fast. With OEM reliability and verified compatibility with the CH13NA02400GAAAA, the HC51KE024 is an inexpensive, high-value part that restores crisp, dependable switching and keeps the system cooling without interruption.

Frequently Asked Questions

Does this Contactor fit my Carrier Model CH13NA02400GAAAA?
Yes. This is the factory-specified OEM contactor for the Carrier Model CH13NA02400GAAAA. 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 CH13NA02400GAAAA?
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.
