The transformer steps line voltage (120V) down to the 24V signal voltage that powers your thermostat, control board, contactor coil, and all low-voltage control functions. When this part fails, the entire control circuit goes dark — the thermostat goes blank, the system won't respond to any calls for heating or cooling, and you may blow a control fuse repeatedly. If your system is completely unresponsive and line voltage checks out at the unit, a failed transformer is the most common cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Factory-matched output for stable low-voltage control operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM transformer, wound to exact VA and voltage tolerances.
