OEM Carrier Contactor C50A406012 Replacement for Model C50A406012

The Carrier C50A406012 contactor is the OEM electrical switch that controls power flow to your HVAC system's compressor and condenser fan motor. When your thermostat calls for cooling, this contactor's coil energizes and closes the contacts, sending line voltage to the outdoor unit; when the call ends, it opens and safely interrupts power. Pitted, burned, or chattering contacts are a leading cause of a unit that won't start or that hums without engaging, so replacing a failing contactor restores reliable operation. This part is engineered to exact OEM specifications for Carrier model C50A406012, ensuring correct amp rating, coil voltage, and pole configuration for a true drop-in fit. Installation is a moderate DIY task for anyone comfortable working with line voltage: shut off power at the disconnect, photograph and transfer the wires one at a time, and seat the new contactor in roughly 20 minutes. We ship same-day on all orders placed before 3PM CST so your repair stays on schedule. Genuine OEM quality means fewer callbacks and longer service life.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A406012?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A406012. 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 C50A406012?
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.
How fast does National HVAC Parts ship?
