The transformer steps down 208\/240V line voltage to the 24V signal used by your thermostat, control board, gas valve, and every low-voltage component in the system. When the transformer fails, the entire control circuit goes dark — no thermostat response, no ignition sequence, no cooling or heating. A faulty transformer is often confirmed by measuring 0V AC on the secondary side while 208\/240V is present at the primary.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part # HT01BD209 | Input: 208\/240V primary | Output: 24V secondary | Power Rating: 40VA | Frequency: 50\/60 Hz | Factory-matched to Carrier PY1PPB036060AAAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to exact factory tolerances, ensuring stable 24V output under full VA load.
