OEM Carrier Contactor C4850C50ZN035600 for HVAC Condenser Unit

Get your Carrier air conditioner switching properly again with this genuine OEM contactor, part C4850C50ZN035600. The contactor functions as the high-current relay that delivers power to the compressor and outdoor fan motor each time the thermostat calls for cooling. Worn or welded contacts are a top cause of no-cool complaints, including a buzzing unit that fails to start and erratic short cycling. This OEM replacement is engineered to the precise contact rating, coil voltage, and pole layout of Carrier model C4850C50ZN035600, ensuring a direct, reliable fit. The repair is a moderate DIY project: turn off power at the disconnect, take a reference photo of the wiring, transfer each conductor to the matching terminal, and fasten the new contactor to its mount. A nut driver and a multimeter are typically all you need. Genuine OEM construction provides the full contact capacity and durability that bargain universal parts lack, preventing premature repeat failures. We stock this part and ship same-day for orders placed before 3PM CST, returning your home to comfortable temperatures as fast as possible.

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?
