Are you sure the thermostat is calling for heat? If you have a programmable thermostat, when was the last time you changed the batteries? I would turn off the power, pull the thermostat off the sub base and put a jumper between terminals R & W. Turn the power back on and see if it wants to come on. Outside of that its time to call the repair man
This is exactly what I've been looking for!

Not much info to go on, but lets look at a few possibilities. Your thermostat could be turned to the ?Fan On? setting, make sure you put it in the ?Auto? mode. Or it could be bad, or there could be a short in the wiring. Open up the access panel on your furnace. Lets eliminate the thermostat from the equation by disconnecting the red, white and if you have a yellow wire at the furnace. Mark down which wire went where. The furnace will have a door safety switch that will have to be taped temporarily closed to test the furnace. With a short piece of wire (2-3" long), strip off 1/2 inch of the insulation on both ends. Secure one end on the R terminal where you removed the red wire from your thermostat. Take the other end and touch the G terminal on the same electrical board. Your fan will start. Don't worry about an electrical shock, the voltage is only 24 volts. Now with one end still attached to the R terminal, touch the W terminal where the white wire was attached. The furnace will now try to fire up. Hold it there until you see that it did start. If you did this and had success, I would say it was your thermostat or the wire going to it. Last resort would be a bad control board. If you want, you can do test your thermostat wiring by removing the thermostat from it's mounting plate. Put all wires back where they were on the furnace. Make sure the access door is back in place and secure. Take that same jumper and jump across the red and white wires on the mounting plate. Again the furnace should start up. Have a helper jiggle the thermostat wires where accessible when the furnace is running and see if it remains on or shuts off. If everything checks out, replace the thermostat. Good Luck!

Sounds like if this is a heat pump, maybe it tripped out on high pressure. Maybe just unplugging the system may reset the control boards. This maybe due to a dirty filter or dirty evaporator coil.

This is no doubt due to failure of the "hot surface ignitor". This device lights the main burners for your furnace, and they fail a lot. I strongly recommend the replacement should be done by a technician.

thats going to be a gas valve issue. either their is no gas to the valve or its not letting it go through. and you also need to make sure the exhaust fan is running too.

It sounds like your defrost board failed. You will need a tech to replace it. With that model it may have a parts warranty but you pay labor(?)
