I performed diagnostic service call on Goodman Air Conditioning Unit. I determined that water got into furnace and in the heat exchanger. With the water inside of the furnace this leads to rusted and cracked heat exchanger as well as being blocked with water. When the heat exchanger is compromised it increases the chance for carbon monoxide poisoning. The circuit board, transformer and blower motor has also failed due to the water. Based on conditions of this furnace it is not safe to run and needs replaced.
