The transformer steps down 120V line voltage to the 24V signal required by your thermostat, control board, and low-voltage control circuit. When the transformer fails, the entire control circuit goes dead — your thermostat shows no response, the system won't call for heating or cooling, and nothing operates despite power being present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | Rating: 40VA | OEM Part Number: HT01CN236 | Direct factory replacement with matched impedance and thermal protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to Carrier's exact VA rating and insulation class. Generic substitutes frequently underperform under sustained load, causing nuisance trips or premature burnout — especially in systems with multiple low-voltage accessories like humidifiers or zoning boards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter to verify 24V output after installation.

Before ordering, confirm your existing transformer's input voltage, output voltage, and VA rating on the data plate inside your air handler cabinet. If your thermostat is unresponsive with line voltage confirmed at the unit, this transformer is the most common cause. Order with confidence — our team is available to verify fitment before you buy.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62909563339123,"sku":"CARRIE-FA4ANC060010AGAA-TRANSFORMER-HT01CN236","price":47.25,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62909563371891,"sku":"CARRIE-FA4ANC060010AGAA-TRANSFORMER-HT01CN236-GEN","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-control-HT01CN236_c3a0a9f9-0f6a-4055-8970-588d3ce4b222.jpg?v=1782940825","url":"https:\/\/nationalhvacparts.com\/products\/carrier-fa4anc060010agaa-transformer-h3hww2","provider":"National HVAC Parts","version":"1.0","type":"link"}
