The contactor is the high-voltage relay that switches power to the compressor and condenser fan motor whenever the thermostat calls for cooling. Pitted, welded, or chattering contacts are a leading cause of a unit that won't start, hums, or short-cycles. This component matches the original coil voltage (24V), pole configuration, and amp rating so it drops straight into the existing bracket and reconnects to the same line, load, and coil terminals. Installation is straightforward for an experienced technician: cut power at the disconnect, photograph the wiring, transfer leads one at a time, and confirm contact pull-in. Using a genuine OEM contactor ensures correct ampacity and reliable engagement, avoiding the premature burnout common with undersized universal parts. In stock and ready to go. Orders placed before 3PM CST ship the same business day, getting your cooling back online quickly. Fitment guaranteed for the HA1AJX024 series condensing unit.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model HA1AJX024000AAAA.\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":62942697095539,"sku":"carrier-contactor-ha1ajx024000aaaa","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-ha1a_fe8e1148-d86e-4d9e-819e-41eff32f0dc4.jpg?v=1781465648","url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-ha1ajx024000aaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
