The transformer steps down 120V line voltage to 24V AC, powering the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the result is a completely unresponsive system: the thermostat goes dark, no calls for heating or cooling are answered, and the unit will not operate at all. A failed transformer is often caused by a short in the low-voltage wiring or a faulty component drawing excessive current.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | Factory-matched OEM design | Part number HT01BD236 | Engineered to exact Carrier electrical specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to precise VA ratings and insulation standards.
