Without a healthy transformer, the brain of your Lennox system has nothing to run on, so a reliable, correctly rated unit is essential to keeping the equipment responsive and safe.\u003c\/p\u003e\u003cp\u003eCommon signs of a failing transformer include a completely unresponsive thermostat, controls that won't power up, a repeatedly blown low-voltage fuse, or an intermittent no-heat\/no-cool condition. A buzzing or scorched transformer, or one that reads no secondary voltage under load, has usually reached the end of its life and should be replaced.\u003c\/p\u003e\u003cp\u003eChoosing OEM matters on Lennox equipment because the 42W94 is spec'd to the exact VA rating, primary\/secondary voltages, and mounting footprint your unit was engineered around. Generic substitutes can be undersized, trip protection devices, or fail prematurely. This factory kit ensures a proper fit and rated performance so your Lennox system runs the way it was designed to.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081106342259,"sku":"LNX-42W94","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-42W94.jpg?v=1783763981","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-transformer-kit-42w94","provider":"National HVAC Parts","version":"1.0","type":"link"}
