When cooling is requested, the low-voltage coil energizes and the contacts close, powering the condensing unit. Contactors wear out as their contacts pit and oxidize, producing symptoms like loud humming, rapid clicking, intermittent operation, or a unit that won't start at all. This part is built to the exact amperage, coil voltage, and pole specifications of Carrier model C50A402052, ensuring a direct, no-modification fit. The replacement is a moderate DIY job: disconnect power at the service box, snap a photo of the wiring, move the leads one at a time to the new contactor, and fasten it in place. Most repairs take about half an hour with basic hand tools. Genuine OEM parts restore factory-grade reliability and help maintain your warranty. This contactor is in stock and ships same-day on orders placed before 3PM CST, so cooling returns fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model C50A402052.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62964562264435,"sku":"carrier-contactor-c50a402052","price":44.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-c50a402052","provider":"National HVAC Parts","version":"1.0","type":"link"}
