Without a healthy transformer, none of the low-voltage controls can operate.\u003c\/p\u003e\u003cp\u003eCommon signs of a failed transformer include a completely dead thermostat, no response when the system calls for heat or cool, repeatedly blown low-voltage fuses, or a burnt-electrical smell from the control compartment. A shorted secondary winding will often take out the fuse the moment power is restored.\u003c\/p\u003e\u003cp\u003eInstalling the OEM Lennox \u003cstrong\u003e39M83\u003c\/strong\u003e ensures the correct VA rating and secondary voltage for your equipment. Under-rated aftermarket transformers can overheat, drop voltage under load, and cause erratic control behavior. This factory-direct part restores reliable 24V control power and protects the rest of your Lennox system.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081107063155,"sku":"LNX-39M83","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-39M83.jpg?v=1783763999","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-transformer-39m83","provider":"National HVAC Parts","version":"1.0","type":"link"}
