The transformer steps down 208\/240V line voltage to the 24V AC signal that powers your thermostat, control board, and all low-voltage components. When this transformer fails, the entire control circuit goes dead — the system will not respond to any thermostat call, and you may measure zero voltage at the 24V secondary terminals or blow the 3A fuse on the control board repeatedly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part # HT01BD209 | Input: 208\/240V, 50\/60 Hz | Output: 24V AC | Power Rating: 40VA | Factory-matched windings and core size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The genuine Carrier OEM transformer is wound to exact VA and voltage tolerances.
