FURNACE STOP WORKING

MY FURNACE STOP WORKING ALL OF A SUDDEN. WHEN I TURNED THE POWER SWITCH TO THE FURNACE OFF AN ON IT BEGAN TO START THEN STOPS. THERE ARE 2 GREEN LED LIGHTS THAT ARE ON. THEY BOTH FLASH FAST. DO ANYONE KNOW WHAT THIS COULD BE. THE FURNACE IS ABOUT 9 YEARS OLD.

    sounds like the same problem i had, do this, you have a igniter on the rt. side of the intake, and a flame sensor on the left. take off the flame sensor and take some fine grit sandpaper and clean the sensor, it does'nt take much, good luck.... kevin
