The control transformer steps down line voltage (120V) to the 24V low-voltage signal required to power your thermostat, control board, contactor coil, and all safety circuit components. When this transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system shows no response, and no heating or cooling operation is possible.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V | Secondary: 24V | Factory-matched OEM part number HT01BD236 | Designed for Carrier C50A502752 commercial packaged unit applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer meets Carrier's exact VA rating, insulation class, and terminal configuration.
