The transformer steps down line voltage (115, 208, or 230V primary) to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, and all safety control logic. When this transformer fails, nothing in the control circuit operates: the system will appear completely dead despite having line voltage at the unit, or you may blow a 3-amp control fuse repeatedly due to a shorted secondary winding.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA | Primary: 115 \/ 208 \/ 230V AC | Secondary: 24V AC | Foot-mounted chassis | OEM Part #HT01AW229 (also referenced as HT01AW229A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier transformers are wound to exact VA and voltage tolerances required by the factory control board.
