The transformer steps down the unit's line voltage to the control circuit voltage required to power the thermostat, control board, and low-voltage accessories. When this transformer fails, you'll typically see a completely unresponsive system — no thermostat display, no blower activation, and no response to any thermostat input. A failed transformer is often the result of a short in the low-voltage wiring or an overloaded secondary circuit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 230V primary voltage | 115V secondary voltage | Totaline OEM factory part | Cross-references: 320659-301, 2-05757-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Totaline OEM transformer, wound to exact factory VA and voltage specifications.
