OEM Carrier Contactor C4850C50AJ05051 for Model C4850C50AJ05051

Keep your Carrier air conditioner cooling reliably with this authentic OEM contactor (C4850C50AJ05051). The contactor is the electromagnetic switch that delivers line voltage to your compressor and outdoor fan motor each time cooling is called for. When it fails, you'll often see a unit that won't start, hear buzzing or chattering, or experience erratic short-cycling—all signs the contacts have worn, pitted, or welded. A correct factory replacement resolves these issues and protects your compressor. Engineered to the exact specifications of Carrier model C4850C50AJ05051, this contactor provides the proper coil voltage, contact rating, and terminal arrangement for a precise fit with no adapters required. Durable silver-alloy contacts resist arcing and stand up to repeated cycling. Installation is a moderate task for a licensed HVAC technician: disconnect power, photograph the wiring, transfer each lead to its matching terminal, and fasten the new contactor in place. Most jobs finish in under 30 minutes. Trust the part Carrier built for your system to restore dependable comfort. In stock and ships same-day on orders before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C50AJ05051?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C50AJ05051. 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 C4850C50AJ05051?
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.
