The 24V coil closes the contacts to pass line voltage to the motors. Over time contacts pit, chatter, or weld, causing no-start conditions, buzzing, intermittent cooling, or a compressor that won't shut off. This 2-pole 30-amp 24V coil contactor matches the factory specification for the CH14NA04200GAAAA, ensuring the correct amperage and coil voltage. A qualified technician can install it in about 20-30 minutes: shut off the disconnect, photograph the existing wiring, transfer the line, load, and coil leads to the same terminals on the new contactor, and secure it. Only basic hand tools are needed. Each contactor is genuine Carrier stock, fully tested, and rated for reliable seasonal duty. Order before 3PM CST and your part ships the same day so cooling is restored fast. Use the correct OEM contactor to prevent repeat no-cool failures.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model CH14NA04200GAAAA.\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":62962607915379,"sku":"carrier-contactor-ch14na04200gaaaa","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-ch14na04200gaaaa","provider":"National HVAC Parts","version":"1.0","type":"link"}
