Coleman Evcon furnace will not ignite? - coleman evcon furnace not igniting

Our model of the furnace Evcon DGAA0708DTB (18 months) will not ignite. We get an error (three lights flashing green) indicates that the switch is not closed combustion. Suggestions? Of course, died in a long weekend, and we are cold here. Any help is greatly appreciated.
