Part number \u003cstrong\u003eHT01AW229\u003c\/strong\u003e is a foot-mounted 60VA step-down transformer that converts line-voltage primary power (115V, 208V, or 230V) to a 24V secondary output — the heartbeat of your system's entire control circuit. When this transformer fails, the thermostat loses power, the control board goes dark, and the system will not respond to any call for heating or cooling. If you're reading no 24V at the secondary terminals, this is the part you need.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA | Primary: 115\/208\/230V | Secondary: 24V | Foot-mounted configuration | OEM part number HT01AW229 (also referenced as HT01AW229A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part — not a generic substitute.
