Why is my furnace blowing cold air?
Check the thermostat (set to HEAT, not COOL), check the fan setting (AUTO, not ON — the ON setting blows air even when the burners aren't firing), and replace the air filter. If those don't fix it, the ignitor, flame sensor, or gas valve may need service.
Is a yellow pilot light dangerous?
Yes. A healthy pilot light is blue. A yellow or orange flame indicates incomplete combustion, which produces carbon monoxide. Turn off the furnace, ventilate the area, and call for professional service immediately. Install CO detectors near all sleeping areas.
