Why is my furnace not heating?

Set the thermostat to heat and above the room temperature. Check whether the system has power and whether the filter needs changing, following the filter instructions for your system.

If it still does not heat, note whether the fan runs or the system makes an unusual sound. Stop using the system if you notice smoke or a burning smell, and call for help.
