OEM Carrier Contactor C50A502512 for Carrier Model C50A502512

This genuine OEM Carrier Contactor (C50A502512) is the magnetic relay that controls line-voltage power to your outdoor unit, energizing the compressor and condenser fan motor whenever your thermostat demands cooling. Produced to Carrier's original factory tolerances, it delivers clean contact closure, low-resistance conductivity, and the rugged durability needed to withstand frequent high-current switching under load. Designed as a direct-fit replacement for Carrier model C50A502512, it matches the unit's coil voltage, pole count, and amperage for a true drop-in installation with no rewiring required. Replacement is an intermediate-level task for a qualified technician: disconnect power at the breaker, snap a photo of the wiring, move each lead to its matching terminal, and fasten the new contactor in place. A failing contactor produces humming, chattering, burnt contacts, or a no-start condition, so installing a fresh one restores reliable cooling and protects your compressor from damage.

Frequently Asked Questions

Does this Contactor fit my Carrier Carrier Model C50A502512?
Yes. This is the factory-specified OEM contactor for the Carrier Carrier Model C50A502512. 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 Carrier Model C50A502512?
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.
