The transformer steps down line voltage to power the low-voltage control circuit that coordinates your system's thermostat, contactor, and safety controls. When this transformer fails, the entire control circuit goes dead — your thermostat will display no power, the system won't respond to any calls for heating or cooling, and there may be a blown fuse or tripped breaker on the secondary side.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA | 230V primary \/ 115V secondary | 50\/60 Hz | OEM part number HT01BC208 | Cross-reference: 320659-301, 2-05757-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Totaline\/Carrier OEM transformer wound to exact factory VA and voltage tolerances.
