The transformer steps line voltage (120V) down to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, and control board. When the transformer fails, absolutely nothing in the control system will respond: the thermostat goes blank, the system won't call for heating or cooling, and no fault codes will appear because the board itself loses power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Factory OEM part number HT01BD236 | Built-in thermal overload protection | Designed for Carrier packaged unit applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage specs for your unit.
