OEM Carrier Contactor C4850C50AY02051 for Model C4850C50AY02051

This genuine OEM Carrier contactor (C4850C50AY02051) is the magnetically operated switch that powers the compressor and condenser fan motor each time your thermostat calls for cooling. Made to Carrier's precise specifications, it ensures firm coil pull-in, low-resistance contact closure, and the rugged durability needed to handle repeated high-amperage starts without pitting or buzzing. It functions as a direct replacement for Carrier model C4850C50AY02051, matching coil voltage, contact rating, and mounting footprint for a no-modification fit. Installation is a moderate-difficulty task for the line-voltage-comfortable DIYer: de-energize at the disconnect, photograph and transfer wires terminal-for-terminal, and fasten the new contactor in place — usually 20 to 30 minutes with basic tools. Replacing a worn contactor restores reliable starts and prevents the compressor strain caused by chattering or failed contacts. Trust OEM parts for the right fit the first time. In stock and ships same-day on orders before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C50AY02051?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C50AY02051. 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 C4850C50AY02051?
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.
