4 blinks is "pressure switch closed" there are 2 in the system according to the wiring diagram one for the vent system  and one for the drain system ... I just wiggled them and heard one "click" the fault light quit blinking and when I pushed the safety switch back in the furnace fired right up.  That being said is there a good website for learning how to maintain your own furnace?  I'll call a pro if I have to, but shoot I can fix a jet engine... this shouldn't be much worse.
Thanks  dan

Your furnace is going into a lockout condition, cycling the power resets the circuit board and it starts over. I will need to know approximate age and model of your furnace, it sounds like you have need to clean the flame sensor rod. However i need to know what i am working with.

What is the make and model of your unit?

Replace the transformer with a 75va resettable transformer.
Check all wiring for a loose connection at the unit and the disconnect and the breaker panel.
Double check ground wires.
Check the low voltage side for a back feed short from a faulty component.
Could be caused from a bad thermostat wire.
Do a continuity reading on stat wires to look for a short.
Do an amp draw reading on the unit to determine an increase in amperage.

no special tricks alyson.....prolly just a breaker or fuse.check the main panel for a turned off breaker and at the unit there's a disconnect box that may have a bad fuse.
