I checked the thermostat, everything looked fine, I went down and looked at the furnace. The pilot bedside light was burning. I pushed the red reset button on the furnace, nil happened. I pushed it again, held it surrounded by for a couple of seconds and it fired up.
It cycled bad, and about 30 min. next, it fired up again just close to it is supposed to, and then wouldn't fire up again.
This time, it took roughly 7 tries before the reset button get it to fire up again.
