I need Goodman igniter Model : GMS80805CNBB Serial : 1404345751 Arrived to no heat. Failed igniter was preventing the furnace from starting. Replaced igniter with universal igniter n could not get the furnace to fire on the first try. Furnace would fire on the second try every time. Need to order Goodman igniter and return. Requesting for Brian H or Mark W to return with me to further look at the heat exchanger. While system was running it rolled out twice. Found a small spot on heat exchanger and would like to get a second opinion.
