Furnace runs but will not ignite
Our furnace started this last night. It will come on and do the blow out thing and then you can hear it click to ignite but it doesn't ignite. After 3 attempts it turns off. Any suggestions?

If you are hearing it click to ignite, then it is not the sail switch as the switch locks out the ignition and you will not hear a click. Most likely problem is the ignitor itself, the gas valve coil, or your gas supply has a problem.
