OEM Carrier Contactor C50A502011 for Model C50A502011

The genuine Carrier C50A502011 contactor is the OEM switch that routes line voltage to your system's compressor and condenser fan motor whenever cooling is needed. Its coil energizes to close the contacts and power the unit, then de-energizes to open them and stop the circuit once the thermostat is satisfied. Pitted or burned contacts often lead to buzzing, intermittent cooling, no-start conditions, or a compressor that won't cycle off. Produced to precise factory standards, this replacement is a direct fit for Carrier model C50A502011 and requires no rewiring to install. A trained technician can usually complete the replacement in under 30 minutes with basic tools after pulling the disconnect, but high-voltage service should always be left to a licensed HVAC professional. Installing the correct OEM contactor protects your compressor from damaging voltage spikes and helps your equipment last longer. We keep this part in stock and ship same-day on orders before 3PM CST. Order today to restore dependable, efficient cooling to your Carrier unit.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A502011?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A502011. 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 C50A502011?
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?
