The control transformer steps line voltage (115, 208, or 230V primary) down to the 24V AC signal used by your thermostat, contactors, and control board. When this component fails, the entire low-voltage control circuit goes dead — the system will not respond to the thermostat, will not call for heating or cooling, and may blow the 3A or 5A control fuse repeatedly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA power rating | 115\/208\/230 VAC multi-tap primary | 24 VAC secondary | 50\/60 Hz | Foot-mount configuration | Factory-matched OEM tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part (FAP).
