Earlier this week, my furnace blower will kick on but not ignite with blower then shutting off. Pulled the cover off the outside and was able to get it going by flipping the reset switch on. Will work fine for awhile then back to the original problem. I have pulled off all the wires one by one and sprayed with contact cleaner. Worked again for a while. Before clicking the reset switch, red light blinked 3 times but would quit when wiggling on the two wires to the reset switch.Then it would go to just blinking once and then quit.

Overnite furnace would cycle on but not blow heat and would turn off. This morning I woke to it working and blowing heatand shut off when thermostat was satisfied. Temp dropped five degrees and would not go on. Manually turned on and off switch at thermostat, blower would go but no ignition.
Any ideas? Circuit board, sail switch, bad wires?
