The transformer converts 120V line voltage down to the 24V AC signal that powers every low-voltage component in the system — the thermostat circuit, gas valve, inducer relay, and control board. When this transformer fails, the furnace goes completely dead: no thermostat response, no ignition attempt, and no error codes on the board. It is often the first component to inspect when nothing on the furnace responds to a call for heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | 120V primary | 24V secondary | 60 Hz single-phase | Compact foot-mount design | Wire lead connections with insulated female quick-connects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer built to exact factory VA and voltage tolerances. Generic units frequently run outside rated VA capacity, causing premature failure of the control board and other low-voltage components — OEM is the only recommended choice for long-term reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and verify with a multimeter before touching any terminals.
