The transformer steps down line voltage (208\/240V) to the 24V low-voltage signal that powers your thermostat, control board, contactors, and every other control-circuit component. When the transformer fails, the entire control circuit goes dark — you'll see a blank thermostat, no fan response, and the system will not respond to any call for heating or cooling.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 208\/240V Primary | 24V Secondary | 40VA capacity | 50\/60 Hz | Replaces HT01BD207, HT01CN232, and 9076-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, wound to exact VA and voltage tolerances.
