A common reason for this is a dirty flame sensor, but it could also be a problem with a blower, the thermostat or a dirty filter. Your furnace may be blinking an error code, which can help diagnose the problem. The list of error codes may be on the inside front panel of your furnace.

We get a lot of questions in the forum about furnaces that blow cold air -- If you'd like to have a contractor take a look at this, we can help you find one, here.
