The transformer steps down 208\/240V line voltage to the 24V signal required to power thermostats, control boards, relays, and all low-voltage components. When the transformer fails, the entire control circuit goes dead — the system won't respond to the thermostat, won't stage heat or cooling, and may blow the low-voltage fuse repeatedly until the root cause is addressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 208\/240V | Output 24V | 40VA power rating | 50\/60 Hz | OEM part number HT01BD209\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and impedance tolerances.
