Our furnace is not working. When we switch the thermostat to blower on it will blow air, but when set to auto it doesnt work. Went and took cover off and there is a red light that stays on? The furnace doesnt seem to ignite?

ok, tested the wires in the thermostat and the furnace kicked on. But when it did, the red light blink 3 times and then 2 slow times. It never did engage the gas to come on. I dont know if we didnt do this long enough for it to kick on? Do you think it could be the thermostat

On the control board jumper R-w.....furnace should work. If not, your problem is at furnace.
