This definite-purpose contactor switches high-voltage power to your compressor and condenser fan motor, energizing the outdoor unit whenever the thermostat demands cooling. Manufactured to precise Carrier specifications, it provides dependable contact closure and long-lasting, arc-resistant operation under heavy cycling loads. The COA0300H2D is matched exactly to Carrier model COA0300H2D, ensuring the coil voltage, amperage rating, and mounting holes align perfectly for a true drop-in fit. Installation is a moderate DIY-level job: disconnect power at the service switch, photograph the wiring for reference, move each lead to the matching terminal on the new contactor, and secure it. Most do-it-yourselfers finish in roughly 30 minutes, though we recommend a licensed HVAC technician for any high-voltage work. Order before 3PM CST and it ships the same day. A worn contactor is a leading cause of AC failure — fix it affordably with genuine Carrier OEM and keep your home comfortable.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model COA0300H2D.\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":62962214207859,"sku":"carrier-contactor-coa0300h2d","price":39.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-coa0300h2d","provider":"National HVAC Parts","version":"1.0","type":"link"}
