Coleman Evcon model dgat056bdd Indicator light flashing 3 times

I can hear the furnace click when I turn up the temp on my thermostat but it never starts blowing, eventually it clicks off again, The indicator light is blinking 3 times.

The draft motor is stuck or inoperative or the pressure switch has failed.... FYI the pressure switch on those units are known to fail. At least that has been my experience.

If this is the model I'm thinking of, there is a motor driven damper in the combustion air passage. If that damper does not open, & they often don't after being shut down for the summer, the furnace will not fire. The damper assembly can be a real bear to get out.
