OEM Carrier Contactor C4850C50AY05111 Replacement HVAC Part

This genuine OEM Carrier contactor (C4850C50AY05111) is the high-voltage switch that powers your air conditioner or heat pump's compressor and condenser fan motor on each cooling cycle. Designed to the exact coil voltage, contact amperage, and terminal arrangement of Carrier model C4850C50AY05111, it offers a precise, drop-in replacement with reliable pull-in and a steady, arc-free connection. A contactor with pitted contacts or a failing coil often shows up as a unit that hums but won't start, short-cycles, or trips without warning, and a new OEM contactor cures the problem. Installation is a low-difficulty task for a qualified tech: kill power at the disconnect, photograph the current wiring, transfer leads one at a time to the matching terminals, and mount the new part. Authentic OEM construction ensures correct fit and dependable longevity that universal substitutes frequently fail to deliver. This contactor is in stock and ships same-day when you order before 3PM CST. Contact our HVAC parts team to verify fit for your specific model.
