OEM Carrier Contactor C4850C50Z8105110 for Model C4850C50Z8105110

The genuine OEM Carrier contactor (C4850C50Z8105110) is the electrically controlled switch that powers your outdoor unit's compressor and condenser fan motor each time cooling is demanded. Produced to authentic Carrier specifications, it ensures reliable contact engagement and durable performance against the repeated high-amperage starts that damage lesser aftermarket parts. This contactor is built specifically for Carrier model C4850C50Z8105110, guaranteeing the correct coil voltage, pole configuration, and current rating for a true drop-in fit. Swapping it out is a moderate-difficulty job: shut off power at the disconnect, photograph and label the wiring, transfer each conductor to the identical terminal, and fasten the new unit. Always confirm your old part number first. A failing contactor commonly causes buzzing, hard starts, or a system that won't cycle off — symptoms this OEM part corrects immediately. It's in stock and ships same-day when you order before 3PM CST, getting your HVAC system back to reliable cooling fast and keeping downtime to a minimum.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C50Z8105110?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C50Z8105110. 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 Model C4850C50Z8105110?
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?
