The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, control board, contactor coil, and every low-voltage safety circuit in the system. When it fails, absolutely nothing works — the thermostat goes blank, the unit won't respond to any call for heating or cooling, and you may find a blown fuse on the control board. It is often the first component to check when an entire system goes dark.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V | Secondary: 24V | Factory-matched OEM replacement | Foot-mount bracket included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to Carrier's exact VA and thermal specifications.
