The transformer steps down high-voltage supply power to the low-voltage control circuit that powers your thermostat, control board, and all 24V system signals. When this transformer fails, the entire control circuit goes dead — the system will not respond to the thermostat, and nothing will turn on. A shorted transformer will also frequently blow the low-voltage fuse on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 230V primary input | 115V secondary output | 50\/60 Hz | OEM part number HT01BC208 | Cross-references: 320659-301, 2-05757-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to exact factory VA and voltage tolerances.
