OEM Carrier Contactor C4850C50ZN030600 for HVAC Condenser Unit

This genuine OEM Carrier contactor, part C4850C50ZN030600, is the heavy-duty relay that powers your compressor and condenser fan motor whenever the thermostat calls for cooling. Constant cycling makes the contactor one of the most common failure points in an outdoor unit; worn contacts lead to chattering, a unit that hums but won't start, or erratic on-off operation. This factory replacement matches the exact coil voltage, contact amperage, and terminal layout specified for Carrier model C4850C50ZN030600, so it installs cleanly with no rewiring guesswork. The swap is a moderate do-it-yourself project: shut off power at the disconnect, photograph the existing wiring, move each conductor one at a time to the matching new terminal, and secure the contactor to its bracket. A nut driver handles nearly every install. Choosing genuine OEM over a one-size-fits-all aftermarket part ensures proper contact gap and amp rating, protecting you from early repeat failures. We keep this contactor in stock and ship it same-day on orders placed before 3PM CST, so your cooling system returns to service quickly. Fitment guaranteed.

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?
