OEM Carrier Contactor C4850C50ZN035100 for HVAC Condenser Unit

This genuine OEM Carrier contactor (part C4850C50ZN035100) serves as the main power switch for your condensing unit, energizing the compressor and outdoor fan motor each time cooling is requested. Because it engages thousands of times per season, the contactor wears quickly, and failing contacts produce symptoms such as a buzzing unit that won't start, short cycling, or no cold air at the registers. This factory replacement is matched to the exact coil voltage, contact amperage, and terminal layout of Carrier model C4850C50ZN035100 for a precise, reliable fit. Most installers rate the job moderate and finish in about 15 minutes: cut power at the disconnect, photograph the wiring, transfer each lead to the matching new terminal, and bolt the contactor to its mount with a nut driver. Opting for genuine OEM over a universal aftermarket part guarantees correct electrical ratings and longer life, preventing the repeat failures that plague low-cost substitutes. We keep this part in stock and ship same-day on orders placed before 3PM CST, so your home is comfortable again fast. Backed by our fitment guarantee.

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?
