It steps down line voltage to the 24V control voltage needed by the thermostat, control board, relays, gas valve, and contactor. Without a healthy transformer, none of the low-voltage circuits can energize, and the system simply won't respond to a call for heating or cooling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms include:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCompletely dead thermostat with no display or response\u003c\/li\u003e\n\u003cli\u003eSystem won't turn on for heating or cooling\u003c\/li\u003e\n\u003cli\u003eBlown control-circuit fuse on the board\u003c\/li\u003e\n\u003cli\u003eA burnt smell or visibly scorched transformer housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e38M45\u003c\/strong\u003e ensures the correct VA rating, primary\/secondary voltages, and mounting for your Lennox equipment.
