The transformer converts 120V line voltage down to the 24V signal required by the control board, thermostat, and all low-voltage safety circuits. When the transformer fails, the entire control circuit goes dead — resulting in a completely unresponsive thermostat, no system call, or repeated blown control fuses.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary input | 24V secondary output | 40VA typical rating | Direct OEM replacement | Mounts to factory bracket with original hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and rated to exact factory VA and insulation class specifications.
