This transformer steps down line voltage from 208\/240V to the 24V AC signal that powers your thermostat, control board, gas valve, and every other low-voltage component in the system. When this part fails, the most common symptom is a completely unresponsive system — no thermostat display, no fan, no heat, no cooling — because the 24V control circuit has lost its power source entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input (Primary): 208\/240V | Output (Secondary): 24V | Power Rating: 40VA | Frequency: 50\/60 Hz | OEM Part Number: HT01BD209 | Direct replacement for HT01CN232\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory-specified OEM transformer, matched to exact VA rating and insulation class required by Carrier.
