The transformer converts 120V line voltage to the 24V signal voltage required to power the control board, thermostat, contactor coil, and all low-voltage control circuits. When it fails, the entire control system goes dark — you'll see a blank thermostat display, no response to heat or cool calls, and no diagnostic fault codes because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Class 2 output | Designed for Carrier C50A304052 commercial rooftop applications | OEM part number HT01BD236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM transformer is wound to exact VA and voltage tolerances for the C50A304052 control circuit. Generic transformers frequently under-deliver VA capacity under load, causing nuisance trips of downstream fuses and shortening contactor coil life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, wire nuts or terminal connectors, multimeter for output voltage verification. Always confirm 24V output before reconnecting control wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty against defects.

Verify your existing transformer's VA rating and primary\/secondary voltages on the unit data plate before ordering. If your fuse or circuit breaker repeatedly trips after transformer replacement, inspect downstream wiring for shorts before installing. Our fitment team is available to confirm compatibility before you order — same-day shipping on all in-stock parts.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62909696246131,"sku":"CARRIE-C50A304052-TRANSFORMER-HT01BD236","price":47.25,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62909696278899,"sku":"CARRIE-C50A304052-TRANSFORMER-HT01BD236-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-HT01BD236_5f5f57d3-7f9c-49e0-adbb-b2db4ee2318e.jpg?v=1782939342","url":"https:\/\/nationalhvacparts.com\/products\/carrier-c50a304052-transformer-h302a1","provider":"National HVAC Parts","version":"1.0","type":"link"}
