Part number \u003cstrong\u003eHT01AW229\u003c\/strong\u003e, this foot-mounted 60VA transformer steps down line voltage (115V, 208V, or 230V primary) to the 24V AC used by your thermostat, control board, gas valve, and all low-voltage control circuitry. When the transformer fails, the entire 24V control circuit goes dead — the system will not respond to the thermostat, the contactor will not energize, and no heating or cooling function will operate. A failed transformer is often indicated by a blown fuse on the control board or a completely unresponsive system despite line voltage being present.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA rating | Primary voltage: 115V \/ 208V \/ 230V AC | Secondary voltage: 24V AC | Foot-mounted configuration | OEM Part #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 and voltage specifications.
