Hi My Furnace Starts and everything then it stops, then it repeats this process over and over what's wrong with it? I have a Goodman furnace, its relatively new the house was built in 2002. Please help it just snowed! IM FREEEZING :( what's wrong with it is it the ignition lighter thing?

Try cleaning the flame sensor with steel wool or fine sand paper.

I cleaned the flame sensor stick and it works now but a day later its doing the same thing again? Is the flame sensor stick need to be replaced?

That is a possibility, If you have a good test meter look at the link below.
