Each time the thermostat calls for cooling, the contactor coil energizes and closes its contacts to start the unit. Over time, contacts pit, weld, or chatter—causing hard starts, buzzing, or a system that simply won't run. Installing this OEM contactor restores clean, dependable switching. Manufactured to exact Carrier coil-voltage and amperage specifications, it fits your model without adapters or rewiring guesswork. Installation is straightforward for a licensed technician, typically 20-30 minutes: cut power, photograph the existing wiring, move leads one at a time, and secure the new contactor in place. We recommend professional installation. As a true OEM component, it provides the longevity and reliability that universal substitutes can't promise. In stock and ready to ship. Orders placed before 3PM CST ship same-day from our warehouse, getting cooling restored fast with genuine Carrier quality and confidence in a proper fit.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model HB1CJX030000AAAA.\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":62942650433907,"sku":"carrier-contactor-hb1cjx030000aaaa","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-contactor-carrier-contactor-hb1c_623619bf-6f51-483e-8f7a-36fe2b482bb1.jpg?v=1781465667","url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-hb1cjx030000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
