I have a furnace that was making some noises overnight. A part was sparking and the furnace wouldn't kick over. It waited a few minutes, same issue. This would happen a few times and eventually work. I have a picture of the part (unsure what it is called). Had about 5-6 wires in, mounted with a copper coil behind the wires. About 2" or 3" footprint and 2" deep.
