OEM Carrier Contactor C50A303011 for Model C50A303011

This OEM Carrier C50A303011 contactor is the genuine factory switching relay that energizes your compressor and condenser fan motor each time your thermostat demands cooling. Its low-voltage coil closes the high-voltage contacts to power the load and opens them to shut the unit down, a cycle it repeats countless times per season. That relentless duty wears the contacts through arcing, leading to humming, hard starts, short cycling, or a unit that fails to start. A genuine OEM C50A303011 restores dependable switching and protects your system's expensive compressor. Manufactured to Carrier's original specifications, it provides an exact match in coil voltage, amperage, and pole count for a direct fit in model C50A303011 — no rewiring or adapters needed. Installation is a quick, moderate job for a qualified technician, typically 20-30 minutes: cut power, transfer the wiring terminal by terminal, secure the new contactor, and confirm operation. Verify coil voltage compatibility first. Order before 3PM CST for same-day shipping and get your cooling system back up and running with minimal downtime.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A303011?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A303011. 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 C50A303011?
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.
