The transformer steps down 120V line voltage to the 24V signal required by the control circuit, thermostat, and low-voltage components throughout the system. When this transformer fails, the entire control circuit goes dead — the thermostat will show no response, the system will not call for heating or cooling, and nothing will operate despite power being present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Class 2 transformer | Factory-matched OEM replacement for part number HT01BD236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage specifications required by Carrier's control board.
