OEM Carrier Contactor C4850C48ZG055900 for Carrier HVAC Units

This authentic OEM Carrier contactor (C4850C48ZG055900) is the high-voltage switching component that powers your compressor and outdoor fan motor on each cooling cycle. Engineered to Carrier's factory tolerances, it ensures reliable coil actuation, solid contact closure, and the exact current rating your equipment requires — eliminating the arcing, pitting, and stuck-closed faults that produce short cycling and complete cooling loss. It is a direct, exact replacement for Carrier model C4850C48ZG055900, so it drops in with no adapters or wiring diagrams needed. Installation difficulty is low for a qualified tech: shut off power at the disconnect, transfer the line, load, and coil wires one terminal at a time to prevent miswiring, then secure the new contactor in the original mount — typically a 15–20 minute job. Installing the genuine OEM part protects your warranty and delivers much longer service life than budget aftermarket relays. Available now and shipping same-day when ordered before 3PM CST.

Frequently Asked Questions

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