The transformer steps line voltage down to the 24V AC control circuit that powers your thermostat, contactor coil, gas valve, and all low-voltage controls. When this transformer fails, the entire control circuit goes dark — the system will not respond to thermostat calls, nothing on the board lights up, and the unit is completely inoperative. A failed transformer is one of the most commonly misdiagnosed problems in the field; always verify 24V output at the secondary before condemning a control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA rating | Primary voltage: 115 \/ 208 \/ 230 VAC | Secondary voltage: 24 VAC | Foot-mount configuration | Factory part number HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, wound to exact VA and voltage tolerances.
