The induced draft motor you describe has a pressure switch proves the induced draft motor is running, it is about 4 inches across and silver and flat and round, it has 2 wires and a tube that atttaches to the induced draft assembly onto a barbed port, this barbed port will obstruct with carbon and needs to be cleared annually with a tiny dril bit or similar device.

Take of the access panel on the furnace and look for a wiring diagram either on the back of the panel or inside the housing. There will be a diagnostic chart on it that will give you a hint what 2 flashes mean. I think it is a "no Ignition" code. If it is, with the access panel off and the door switch taped in the closed position, the furnace will try to start if the thermostat is calling. You want to look at the control module to see if it is flashing, then you should notice a small fan that pushes out the combustion products start to turn. Then if you look in a small view port, you should see an orange glow followed by a clicking noise at the gas valve. Then you should notice a blue flame in the view port. This flame must stay on for 5-6 seconds or the unit will turn it self off. If one of these do not happen, you will need a technician to troubleshoot it. Check to see if all wires and hoses are tight and in place. Make sure your condensate hoses are not blocked and free of water. Make sure there is no blockage in your vent pipe(s).
