OEM Carrier Contactor C4850C50AK06021 for Model C4850C50AK06021

Keep your Carrier unit switching reliably with this OEM contactor (C4850C50AK06021), the genuine relay that sends line voltage to the compressor and condenser fan motor on every cooling cycle. Engineered to factory standards for Carrier model C4850C50AK06021, it delivers the correct coil voltage and contact rating, giving you crisp engagement instead of the buzzing and welded contacts typical of aftermarket parts. A failing contactor commonly causes an outdoor unit that hums without starting, won't shut down, or trips the breaker. The replacement is a moderate DIY project: cut power at the disconnect, snap a photo of the wiring, move each lead over individually, then remount — about 20–30 minutes with a nut driver and screwdriver. Installing the exact OEM component protects both system performance and warranty coverage. This contactor is in stock and ships the same day on orders placed before 3PM CST, so your comfort is restored with minimal downtime. Trust genuine Carrier parts for a dependable, long-lasting repair.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C50AK06021?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C50AK06021. 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 C4850C50AK06021?
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.
