When the thermostat calls for cooling, the contactor's coil energizes and closes the contacts, delivering high-voltage power to start your system. Worn or pitted contacts cause hard starts, buzzing, or a unit that won't run—replacing this part restores clean, reliable switching. Engineered to exact Carrier specifications for the correct coil voltage and amperage rating, it drops right into your model without modification. Installation is straightforward for a qualified technician, typically 20-30 minutes: shut off power, photograph the wiring, transfer leads one at a time, and mount the new contactor. We recommend professional installation. As a true OEM part, it delivers factory performance and longevity that universal replacements can't guarantee. In stock now—orders placed before 3PM CST ship same-day from our warehouse so you can get cooling restored fast with genuine Carrier reliability and peace of mind.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model HB1CJX036000AAAA.\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":62942650138995,"sku":"carrier-contactor-hb1cjx036000aaaa","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_affbf07a-51e2-4453-a7a6-926824fdc4f4.jpg?v=1781465669","url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-hb1cjx036000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
