A tree was struck by lightning outside of our home. The neighbors furnace and our furnace was damaged and shows no sign of life. The neighbor's furnace needed the main circuit board replaced and then their furnace worked. Our furnace had power coming out of the transformer but the green light was not on or blinking. We replaced our circuit board and now our green light is on but nothing happens. Even if you bypass the thermostat still nothing happens. Any help would be greatly appreciated. This is a concord 80% efficiency gas furnace.
