The transformer steps line voltage (120V) down to the 24V signal voltage that powers your thermostat, contactor coil, and all low-voltage control wiring. When this component fails, the entire control circuit goes dead — the thermostat loses power, the contactor never energizes, and the system will not respond to any call for cooling. It is often the first component to check when nothing works at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | Primary: 120V | Secondary: 24V | OEM part number HT01AW229 | Factory-matched impedance and thermal protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to exact factory VA and voltage specifications.
