The transformer steps down 208\/230V line voltage to the 24V DC signal that powers your thermostat, control board, gas valve coil, and contactor coil. When this part fails, the entire low-voltage control circuit goes dead — the thermostat goes blank, the system will not respond to any call for heating or cooling, and no error codes are generated because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | 208\/230V primary input | 24V secondary output | 50\/60Hz | OEM part number HT01BD209 | Also replaces HT01BD207, HT01CN232, and 9076-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances for the Carrier PY2PNB024060NC.
