I can turn the heater on and the small fan will come on and littlered light will blink 3 times but the heater will not ignite. How do I correct the problem?

If you look at the wiring diagram in your furnace you will see that 4 blinks means there is either a blockage of air or your room air blower is not working. Check the air filter for any debris first. Then test the room air blower to see if it turns on and blows enough air prior to going out on code. Are all the dampers open both in the pipes as well as at the registers?
