It converts 120V line voltage to the 24V AC signal that powers every low-voltage component in the system — including the thermostat, gas valve, inducer relay, and control board. When the transformer fails, the result is unmistakable: the thermostat goes completely dark, the furnace does not respond to any call for heat or cooling, and no low-voltage components function at all. A failed transformer is often caused by a short in the secondary low-voltage circuit, so always inspect wiring and fuses before installing a replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary input | 24V AC secondary output | 40VA rating | Foot-mount configuration | Wire-lead connection type | 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound to exact factory VA and voltage tolerances. Undersized or off-tolerance generic transformers can overheat, trip thermal cutoffs, and leave low-voltage components voltage-starved — shortening the life of your control board and gas valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off all power at the breaker before beginning.
