OEM Carrier Contactor C50A303051 for Model C50A303051

This genuine OEM Carrier C50A303051 contactor is the electrically operated switch that powers your unit's compressor and condenser fan motor on every cooling cycle. A 24-volt coil closes the high-voltage contacts to start the load, then releases to stop it, making the contactor one of the most frequently replaced components in an HVAC system. Over time, arcing pits the contact surfaces, leading to chatter, hard starts, or a complete failure to run. Installing the OEM C50A303051 restores clean, reliable switching and helps prevent further damage to your compressor. Manufactured to Carrier's exact specifications, it matches the original part's coil voltage, amperage, and pole layout for a precise fit in model C50A303051 with no modifications required. The replacement is a moderate DIY or quick professional job — around 20-30 minutes — involving a power disconnect, careful wire transfer, and an operational check. Verify your coil voltage before installing. Order before 3PM CST to get same-day shipping and have your cooling system running again as quickly as possible.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A303051?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A303051. 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 C50A303051?
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?
