american standard freedom 80 single stage furnace
 
I have an american standard freedom 80 single stage furnace. It is running like normal except it's blowing cold air. What's my 1st step? I opened lower panel and checked for loose wires so far. The LED light is flashing 4 times. What does this code mean?

Check the vent pipes outside for blockage if it is a high efficiency furnace. Post the model # and pics of it so we know which one it is.
