    Model dgat056bdd if you have a coleman evcon furnace I had mine go out well it was the sensor probe it right by the flame well it would light for about 60 sec. then go out it would do this about 4 to 5 times then this light would blink one time in which it means "ignition failure" well what I found out is that the sensor probe looked the same but the thickness of the metal has to be the same to you see the sensor probe is verey verey sensitive so I moved it closer into the flame also I learned that on the control board right near the little lite that you will see two little black square if you look close there is tempture setting that you can adjust . Just by pulling up on them and moving it to your tempture don't for get to use a owm meter to make sure you don't have any broke wires if you use a owm meter turn the power off!! My furnace is working good now
