Question about Heating & Cooling
So It turns on for a few seconds and then turns off again. While its on, it blows warm air just fine and all that its just that it only stays on for 5 seconds at the most.
I am a furnace technician and to solve the problem.You will find on the opposite side of the ignitor their is a flame rod with a wire connected to it.Remove it and clean it with sandpaper and re install it and it should fix the problem.If this is dirty it won't sense ignition and the board thinks that is it introducing raw gas into furnace and it isn't igniting and shuts off as a safety precaution.If you see a blueish tinge on the flame rod you should probably replace it.

Check the flu. It has an outer pipe for fresh intake air and an inner pipe that allows the cumbusted air vent out. If the inner pipe is rusted through it sucks the combusted gas back into the fresh air side and flame dies off due to the lack of oxygen and shuts off the gas valve.

Gas direct vent units such as these (not sure what model you have) typically have a thermocouple, or if the thermostat is mounted away from the unit, a thermopile. Either of these could be defective or in some cases, the valve is bad. Make sure there is no obstruction at the vent outside as well, as this will cause the unit to shut off due to lack of combustion air.
