OEM Carrier Contactor C50A303012 for Model C50A303012

The genuine OEM Carrier C50A303012 contactor is the magnetic switch responsible for delivering line voltage to your compressor and outdoor fan motor on every call for cooling. A 24-volt coil draws the contacts together to energize the load and releases them to de-energize it, cycling continuously throughout the cooling season. This heavy duty makes the contactor a frequent wear item; arcing eventually pits the contacts, causing chatter, intermittent cooling, or a unit that simply won't run. Swapping in the OEM C50A303012 restores reliable switching and helps prevent compressor damage from poor electrical contact. Engineered to Carrier's exact specifications, it matches the factory coil voltage, amp rating, and pole arrangement for a precise, no-modification fit in model C50A303012. A trained tech can complete the replacement in about 20-30 minutes — disconnect power, move each wire to the matching terminal, mount the contactor, and verify clean pull-in and operation. Always check coil voltage before installing. Order before 3PM CST and your contactor ships the same day, getting your HVAC system cooling again fast.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C50A303012?
Yes. This is the factory-specified OEM contactor for the Carrier Model C50A303012. 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 C50A303012?
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?
