If you are not a trained HVAC tech it is important that you find a certified tech in your area to properly diagnose and fix the problem as it could be dangerous to do it on your own as well as make the problem worse.
However, it is helpful to look to see if you are getting an error or fault code (some brands call it a fault code while others call it an error code). If you go to this site you can find a list of error codes as well as links to installation manuals and more: http://www.sbeelectricandhvac.com/trane-furnace-xb80-diagnostic-led-code/.
Beyond this it is hard to say what the issue is. It could be a fault with the thermostat (not receiving the signal to heat) or for some reason there is a mechanical issue preventing the burners from igniting or that is shutting them down as a safety feature.
In any event, you will need an HVAC tech to come and diagnose the problem and fix it. To find a certified in your area you can go here: http://www.furnacecompare.com/perl/find_contractors.pl.
Hope this helps.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
