{"product_id":"oem-lennox-control-transformer-96c79","title":"OEM Lennox Control Transformer — 96C79","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e96C79\u003c\/strong\u003e transformer supplies the low-voltage control power that keeps your Lennox furnace or air handler operating. It steps incoming line voltage down to the 24V used by your thermostat, control board, gas valve, and relays. Without a healthy transformer, none of the low-voltage circuits in your system can function, making this a critical component in the control chain.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A failed \u003cstrong\u003e96C79\u003c\/strong\u003e transformer often shows up as a completely unresponsive thermostat, no 24V at the control board, a blown low-voltage fuse, or a system that won't power up at all. Overheating, a burnt smell, or a short in downstream wiring can cause the transformer windings to open or short internally.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox control circuits are engineered for precise voltage and VA ratings. An OEM \u003cstrong\u003e96C79\u003c\/strong\u003e guarantees the correct secondary output, mounting footprint, and terminal configuration for a direct, worry-free fit — protecting sensitive boards and valves from over- or under-voltage that generic substitutes can introduce. Choosing the factory part preserves your system's reliability and rated performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081091006835,"sku":"LNX-96C79","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-control-LNX-96C79.jpg?v=1783760000","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-control-transformer-96c79","provider":"National HVAC Parts","version":"1.0","type":"link"}
