Its low-voltage coil energizes heavy-duty contacts that route line voltage to the compressor and outdoor fan motor whenever the thermostat calls for cooling. As the contacts age they pit, weld, or chatter, causing no-cool complaints, hard starts, and scorched control wiring. Installing this precise replacement restores dependable engagement and protects the compressor from harmful voltage conditions. Matched to Carrier's original coil voltage, amperage, and mounting footprint, it drops directly into the LC748LCCSRLYX2100 with no rewiring or bracket modification. The swap is easy for a qualified technician and typically takes 15 to 20 minutes: open the disconnect, label and move the wires one at a time, mount the new part, and re-energize. Always confirm power is off before servicing. We keep this contactor in stock and ship same-day on all orders placed before 3PM CST so your repair finishes without delay.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC748LCCSRLYX2100.\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":62942602461555,"sku":"carrier-contactor-lc748lccsrlyx2100","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-contactor-carrier-contactor-lc74_9e8a7d44-4029-4ee8-bf2e-4d1c15efd6c8.jpg?v=1781466134","url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-lc748lccsrlyx2100","provider":"National HVAC Parts","version":"1.0","type":"link"}
