OEM Carrier Contactor C50A405063 for Model C50A405063

The genuine Carrier C50A405063 contactor is the OEM switching relay that delivers high-voltage power to your system's compressor and condenser fan motor. Each cooling cycle, the coil energizes and closes the contacts to start the unit, then opens them to cut power when the thermostat is satisfied. Over time the contact points burn and pit, causing symptoms such as buzzing, intermittent cooling, failure to start, or a compressor that won't shut off. Built to precise factory tolerances, this replacement fits Carrier model C50A405063 exactly and installs without modification. A skilled technician can typically complete the swap in less than 30 minutes using standard tools after locking out power, though high-voltage repairs should be handled by a licensed HVAC professional. Fitting the correct OEM contactor protects your compressor from electrical damage and helps prolong the life of your equipment. We stock this part and ship same-day on orders placed before 3PM CST. Order today to restore reliable, efficient cooling to your Carrier system with a part engineered to OEM standards.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A405063?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A405063. 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 C50A405063?
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?
