This NEMA Class II heavy-duty end-bell transformer is built to Lennox factory specifications for reliable, continuous low-voltage supply across compatible Lennox equipment.\u003c\/p\u003e\u003cp\u003eWhen a control transformer fails, the low-voltage circuit loses power — resulting in an unresponsive thermostat, a system that won't start, tripped or blown control fuses, or a burnt-smelling, discolored transformer body. Repeated fuse failures often point to a shorted or overloaded transformer that needs replacement.\u003c\/p\u003e\u003cp\u003eUsing the OEM \u003cstrong\u003e26P00\u003c\/strong\u003e ensures the correct VA rating, primary voltage, and mounting configuration for your Lennox unit. Undersized or mismatched aftermarket transformers can overheat, drop voltage under load, and cause intermittent control faults. The factory-rated 26P00 delivers stable 24V output and the durable heavy-duty construction Lennox systems are designed around.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081079210355,"sku":"LNX-26P00","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-26P00.jpg?v=1783759055","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-24v-control-transformer-26p00-mars-50320","provider":"National HVAC Parts","version":"1.0","type":"link"}
