My flame went out on my furnace and I saw a green flashing light , with a red button below it. I hit the red button and the green light went away, so I hit the red button again and furnace fan kicked on and then burner light. It through a cycle heating the house to proper temp. and when the furnace was suppose to turn back on through the thermostat, the green light started to flach again and I can not reset it again. I hold the red buuton in and when the green light goes out but when I release the red button the green light keeps flashing... I need a little guidance before I call the repair man... thanks Shawn
