The transformer steps down 120V line voltage to the 24V signal used by your thermostat, control board, and safety circuits. When it fails, the entire low-voltage control circuit goes dead — your thermostat loses power, nothing responds, and the system won't start at all. A failed transformer is one of the most common causes of a completely unresponsive HVAC system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Class 2 transformer | Factory-matched OEM replacement for part# HT01CN241\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact factory specifications, ensuring proper VA capacity for all connected loads.
