The transformer steps down high-voltage line power — 120, 208, or 240 VAC — to the low-voltage 12\/24V AC signal that powers your system's control board, thermostat, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dead: the thermostat goes blank, the system refuses to respond to any call for heating or cooling, and circuit breakers may trip if the secondary is shorted. Replacing the transformer with the correct OEM part restores full system communication and protects downstream components from voltage irregularities.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary: 120\/208\/240 VAC | Secondary: 12\/24V AC | Single-phase | 60 Hz | Factory-matched Carrier\/Totaline specification (P201-35150)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances specified by Carrier engineering.
