OEM Carrier Contactor C4850C48ZN055900 for Model C4850C48ZN055900

This OEM Carrier contactor (C4850C48ZN055900) is the genuine electromechanical switch that supplies line voltage to your air conditioner's compressor and outdoor fan motor. When the thermostat requests cooling, the coil draws in and closes the contacts to energize the system, then releases to safely break power once the demand is met. Made to original factory specifications, this contactor provides the exact amperage, coil voltage, and pole configuration required for Carrier model C4850C48ZN055900, correcting common failures including welded or pitted contacts, loud humming, intermittent starting, or a unit that won't power down. Installation difficulty is moderate: turn off power at the disconnect, label and transfer the wiring, mount the replacement, and reconnect — typically a 30-minute job with basic tools. Be sure the circuit is de-energized before servicing. Genuine Carrier parts deliver dependable performance and longer service life than off-brand options and help preserve your equipment warranty. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model C4850C48ZN055900?
Yes. This is the factory-specified OEM contactor for the Carrier Model C4850C48ZN055900. 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 C4850C48ZN055900?
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.
