Furnace is Running Again
O ur furnace was fixed this afternoon and it is now heating the house again so that is very good news. There is one more part he wants to replace... just a small contact cap that goes in the ignition transformer... but he didn't have one on his truck. He is off tomorrow but said he will stop by in the morning to install a new contact cap. I don't really know the name of this part but it is an electrical contact point in the shape of a small cap so I'm calling it a contact cap here. This older corroded contact cap is giving us inaccurate resistance readings. These readings give a reading in ohms indicating the brightness of the flame. The lower the resistance, the brighter the flame. He adjusted the fuel pump to get the best resistance numbers possible but he's thinking the numbers will be even lower with a contact cap that is in better condition. This is important because the ignition control box will shut down the furnace if these readings are too high. Too h
