Ignition failure code on my furnace

I am getting an ignition failure code on my coleman evcon furnace. I have already cleaned the flame sensor with a 220 grit sandpaper. The problem remains. The unit calls for heat from the tstat, the ignitor glows bright orange, the flame ignites and i can see it thru the observation hole, then just as the blower motor kicks on the flame goes out. PLEASE HELP I AM COLD!

    I have a coleman Model DGAT070BTE that will glow and then ignite, but when the blower kicks on the flame goes out. I have already cleaned the sensor unit off with steel wool. I did notice a small break in the insulation of the yellow wire going to the sensor unit, located about 3/4" from the aft end of the sensor.

SOURCE: Have a Evcon Coleman Furnace shows three green

I have had the same problem with mine for the last 2 years. Remove the motor on the side of the furnace(usually held on by 3 screws) and turn the fan blades inside by hand. after sitting all summer it seems to get stuck. If it moves freely, replace the motor and try to start it again. This fixed mine the last 2 years! Hope this helped.

Hello,

So the furnace will come on and heat sometimes ? Then other times it will click but not heat ?

Check for fault codes if it has them and make sure it is clean inside burner tubes and clean the flame sensor.

I have a coleman evcon furnace and it wont work it gives me a flash code of 1 what does it mean


One flash mean ignition failure. The sequence is: T-Stats calls for heat, inducer motor comes on, igniter glows orange (look through glass), then gas comes on and burner lights, approximately 1 minute later the indoor blower comes on. If you don't see the glow, most likely the igniter is bad. If you see the glow but no flame, it's a gas problem, supply or defective valve.

Burner flame going out on windy days on Coleman Evcon LP furnace


This sounds like a bad heat exchanger. It is possible that you do not see the crack because the crack is closed when the heat exchanger is cold (or room temp). Allow the furnace to heat up, this will allow the expansion of the crack. Turn the power off and examine the heat exchanger while it is still hot.
