It's a small but critical component — when it stops delivering clean secondary voltage, the entire control side of your Lennox system goes dark.\u003c\/p\u003e\u003cp\u003eTypical failure symptoms include a dead thermostat display, a furnace or air handler that won't respond to a call for heat or cool, and low-voltage fuses that blow immediately after replacement. A transformer that hums loudly, runs hot, or shows scorching or swelling is a clear candidate for replacement.\u003c\/p\u003e\u003cp\u003eOEM matters here because the 42W93 is matched to your Lennox unit's exact VA rating, voltage taps, and mounting configuration. An off-spec aftermarket transformer can overheat, overload the circuit, or fail early. This factory-correct replacement guarantees proper fit and dependable, rated performance so your Lennox equipment powers up and operates as intended.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081106375027,"sku":"LNX-42W93","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-42W93.jpg?v=1783759998","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-control-transformer-42w93","provider":"National HVAC Parts","version":"1.0","type":"link"}
