The transformer steps down line voltage from 230V primary to 115V secondary at a \u003cstrong\u003e40VA\u003c\/strong\u003e rating, powering the low-voltage control circuit that operates the thermostat, relays, and safety switches throughout the system. When the transformer fails, the entire control circuit loses power — resulting in a completely unresponsive system, a tripped breaker, or a blown fuse on the secondary side.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 230V primary | 115V secondary | 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 Totaline\/Carrier OEM transformer wound to exact factory VA and voltage tolerances.
