The transformer steps down line voltage from 208\/240V to the 24V AC signal that powers your thermostat, control board, gas valve, and every other low-voltage component in the system. When this part fails, the result is typically a completely unresponsive system — no call for heat or cool, no contactor pull-in, no display activity — because the entire 24V control circuit loses power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 208\/240V primary | 24V secondary | 40VA power rating | 50\/60Hz compatible | Factory-matched OEM tolerances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage specifications.
