The control transformer steps down line voltage (115, 208, or 230V) to a safe 24V signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the result is total system lockout: nothing responds, no thermostat signal reaches the unit, and the system appears completely dead. It is one of the first components to check when a unit shows zero control-circuit activity.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA rating | Primary: 115\/208\/230V multi-tap | Secondary: 24V | Foot-mounted design | OEM part number HT01AW229 \/ HT01AW229A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part built to exact VA tolerance.
