The transformer steps down line voltage (120V) to the 24V AC signal that powers your thermostat, control board, and all low-voltage safety circuits. When the transformer fails, the entire control circuit goes dark — your thermostat goes blank, the system stops responding to calls for heating or cooling, and no fan or blower operation occurs. A failed transformer is often misdiagnosed as a bad control board, so always verify transformer output voltage before replacing costlier components.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary → 24V secondary | Factory OEM part number HT01CN241 | Exact-fit mounting and lead configuration for FZ4ANP024L05AAAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM transformer, wound to exact VA and voltage tolerances.
