The transformer steps down 120V line voltage to the 24V AC signal required by your thermostat, contactor coils, and control board. When this component fails, the entire low-voltage control circuit goes dead — your thermostat goes blank, the system stops responding to calls for heating or cooling, and no safety components can operate. It is often the first part to inspect when \u003cem\u003enothing\u003c\/em\u003e on the system responds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | OEM part number HT01BD209 | Factory-matched construction for Payne PA2PPB030000AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine OEM transformer built to Payne's exact VA rating and insulation class.

Verify your existing transformer's primary voltage, secondary voltage, and VA rating on the unit data plate or existing component label before ordering. If your control fuse keeps blowing after replacement, inspect for wiring shorts before condemning the transformer. Our team is available to verify fitment — call or chat before you order.\u003c\/p\u003e","brand":"Payne","offers":[{"title":"OEM","offer_id":62908919480691,"sku":"PAYNE-PA2PPB030000AA-TRANSFORMER-HT01BD209","price":34.95,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62908919513459,"sku":"PAYNE-PA2PPB030000AA-TRANSFORMER-HT01BD209-GEN","price":30.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-HT01BD209_83629018-19a7-4b65-8a59-960671204eff.jpg?v=1780718940","url":"https:\/\/nationalhvacparts.com\/products\/payne-pa2ppb030000aa-transformer-h30291","provider":"National HVAC Parts","version":"1.0","type":"link"}
