OEM Carrier Contactor C50A502051 for Model C50A502051

The genuine Carrier C50A502051 contactor is the OEM relay that switches high-voltage power to your system's compressor and condenser fan motor. Each time the thermostat calls for cooling, the contactor coil pulls in and closes its contacts to energize the unit, then releases to break the circuit when cooling stops. Over time the contact points pit and burn, leading to buzzing, intermittent operation, failure to start, or a compressor that won't shut off. This factory-spec replacement is an exact fit for Carrier model C50A502051 and installs without any wiring modifications. For a qualified technician the swap is a quick job — usually under 30 minutes with hand tools once power is safely disconnected — but high-voltage repairs should be handled by a licensed HVAC pro. Choosing the correct OEM part safeguards your compressor against voltage spikes and keeps the system running efficiently. We keep this contactor in stock and ship same-day on orders placed before 3PM CST. Order today and restore dependable cooling with a part engineered to factory standards.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A502051?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A502051. 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 C50A502051?
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?
