The transformer steps down line voltage from 120V to 24V to power the control board, thermostat, and all low-voltage safety circuits throughout the system. When it fails, the result is total loss of control — a blank thermostat, an unresponsive system, or a tripped fuse on the secondary circuit. If your Carrier unit powers on but does nothing, a failed transformer is often the first component to test.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V | Secondary: 24V | OEM Part Number: HT01BC116 | Direct factory-matched replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the Carrier control board.
