{"product_id":"oem-lennox-wire-harness-76m80","title":"OEM Lennox Wire Harness — 76M80","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e76M80\u003c\/strong\u003e wire harness is the pre-assembled wiring loom that routes power and control signals throughout your Lennox furnace, air handler, or condensing unit. It arrives with the correct conductors, connectors, and terminals already installed, giving you a direct, plug-in replacement for damaged or aged factory wiring.\u003c\/p\u003e\u003cp\u003eA deteriorating harness commonly shows up as intermittent equipment operation, unexpected error codes, components that won't energize, repeatedly blown fuses, or the smell of overheated insulation at a connector. These electrical faults frequently masquerade as a bad control board or motor, so a fresh harness can be the fix that finally clears a persistent no-heat or no-cool fault.\u003c\/p\u003e\u003cp\u003eThe OEM \u003cstrong\u003e76M80\u003c\/strong\u003e harness matters because Lennox specifies exact wire gauge, length, and connector keying for each application. Substitute wiring or field splices invite loose pins, corrosion, and voltage drop that can damage expensive downstream components. This factory replacement drops in cleanly, preserving proper polarity, system reliability, and your equipment warranty.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081141666163,"sku":"LNX-76M80","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-wiring-harness-multipin-LNX-76M80.jpg?v=1783764162","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-wire-harness-76m80","provider":"National HVAC Parts","version":"1.0","type":"link"}
