OEM Carrier Contactor C4850C50AY04051 Replacement HVAC Part

Restore reliable starts to your Carrier equipment with this genuine OEM contactor (C4850C50AY04051), the electrically controlled switch that feeds high-voltage power to the compressor and condenser fan motor on a cooling call. Engineered to match the coil voltage, contact rating, and terminal layout of Carrier model C4850C50AY04051, it installs as a true replacement and delivers clean, dependable pull-in every cycle. A failing contactor is among the most frequent reasons a unit hums without starting, short-cycles, or trips at random, and a new OEM part puts an end to those symptoms. Installation is low-difficulty for a trained tech: disconnect power, photograph the wiring, move each lead to its matching terminal, and mount the new contactor securely. Authentic OEM construction means the precise fit and long-lasting performance that generic substitutes often can't match. We keep this contactor in stock and ship same-day on orders placed before 3PM CST. Our HVAC parts team can help verify compatibility with your unit before you buy.
