OEM Carrier Contactor C4850C50AK03011 for Model C4850C50AK03011

This authentic OEM Carrier contactor (C4850C50AK03011) is the line-voltage switch that energizes your compressor and condenser fan motor each time your system calls for cooling. Built to original factory standards, it delivers consistent switching performance, resists arcing and contact pitting, and resolves issues like a humming unit, a system that won't start, or one that fails to cycle off. Designed as a direct-fit replacement for Carrier model C4850C50AK03011, it matches the factory coil voltage, amperage, and pole configuration, eliminating any need for rewiring or adapters. Installation is moderate and usually takes about 15-20 minutes for a qualified technician: shut off power, photograph the wiring, transfer leads one at a time, and secure the new contactor. Line-voltage work should be performed by a licensed HVAC professional. Every part is brand-new, never reconditioned, and backed by our quality guarantee. Order before 3PM CST and we ship same-day to get your equipment running again fast. NationalHVACParts.com is your trusted source for genuine Carrier components.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C50AK03011?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C50AK03011. 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 C4850C50AK03011?
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?
