OEM Carrier Contactor C4850C50Z2040100 for HVAC Condenser Unit

The genuine OEM Carrier contactor (C4850C50Z2040100) is the high-current relay that powers your compressor and condenser fan motor every time your thermostat signals for cooling. As the contacts wear, pit, or weld over thousands of cycles, you'll notice a buzzing outdoor unit, a compressor that struggles to start, or cooling that comes and goes. Made to exact Carrier factory specifications for model C4850C50Z2040100, this replacement provides the matching coil voltage, contact rating, and pole configuration of the original for a clean, direct installation. This is a moderate-skill DIY repair: shut off power at the disconnect, photograph and transfer the wiring one lead at a time, then secure the new contactor — usually a job of under thirty minutes. Installing the true OEM contactor protects your compressor investment and preserves warranty coverage, avoiding the early failures seen with generic parts. This contactor is in stock and ships the same day on all orders placed before 3PM CST. Keep your Carrier system cooling dependably with the precise contactor it was built to use, delivered quickly and backed by genuine OEM 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?
