OEM Carrier Contactor C4850C50AK04051 for Model C4850C50AK04051

This genuine OEM Carrier contactor (C4850C50AK04051) is the electromechanical switch responsible for delivering line power to your compressor and outdoor fan motor each time the thermostat demands cooling. Built to authentic Carrier factory tolerances, it delivers consistent, low-resistance switching and long-lasting reliability against the demanding startup loads of residential and light-commercial systems. Engineered specifically for Carrier model C4850C50AK04051, this contactor drops in directly with the proper coil voltage, pole arrangement, and contact rating. Pitted, welded, or chattering contactors are among the top reasons an outdoor unit fails to start, buzzes, or short-cycles. The swap is quick for an experienced technician—about 20 to 30 minutes to kill the power, photograph and move the wires one at a time, and fasten the replacement in place. Installing the correct OEM part helps preserve equipment performance and warranty protection. This contactor is in stock and ships same-day on orders received before 3PM CST, so your air conditioning is back up fast. Sold and supported by NationalHVACParts.com.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C50AK04051?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C50AK04051. 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 C4850C50AK04051?
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.
