There can be several reasons your not igniting. You may have a dirty filter, safety switch engaged etc. There is a diagnostic light in the bottom compartment that flashes a code. see what code it is flashing and post that info. The breakdown for the code is on the back of your door.
First make sure nothing is blocking your intake or exhaust vents both inside and outside of the home. Next, try removing the rubber tube that goes from the "vent motor" to the pressure switch(circular device with two wires going to it as well as the rubber tube) and sucking on it while leaving it connected to the pressure switch. By sucking on it you may free the diaphragm inside the pressure switch if it is sticking.
