Its job is critical: step down the high-voltage line power (115\/208\/230V) to a safe 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, reversing valve, and all safety switches. When this transformer fails, \u003cem\u003enothing\u003c\/em\u003e responds. The thermostat goes blank, the system refuses to energize, and no fault codes appear because the control circuit itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA capacity | Primary voltage: 115\/208\/230V AC | Secondary voltage: 24V AC | Foot-mounted configuration | Factory-matched output tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to Carrier's exact VA rating and voltage tolerance.
