OEM Carrier Contactor C4850C50Z2055100 for HVAC Condenser Unit

This genuine OEM Carrier contactor (C4850C50Z2055100) acts as the primary power switch for your outdoor condensing unit, closing to drive the compressor and fan motor whenever cooling is requested. Worn contactor contacts are a leading cause of HVAC service calls — symptoms include a humming unit that won't start, intermittent cooling, or audible chattering at the outdoor cabinet. Built to exact Carrier factory specifications for model C4850C50Z2055100, this replacement provides the correct coil voltage, contact amperage, and pole count of the original for a clean, direct fit. The job is a moderate-skill DIY repair: disconnect power, photograph and transfer the wiring one lead at a time, and secure the new contactor in minutes. Choosing the true OEM component preserves your compressor's life and warranty, avoiding the early failures typical of low-cost generic switches. We stock this contactor and ship it the same day on all orders placed before 3PM CST. Get your Carrier system cooling consistently again with the precise contactor it was engineered to use, shipped quickly and backed by genuine OEM reliability and quality.

Frequently Asked Questions

Does this Contactor fit my Carrier HVAC Condenser Unit?
Yes. This is the factory-specified OEM contactor for the Carrier HVAC Condenser Unit. 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 HVAC Condenser Unit?
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?
