Does anyone know what would cause my furnace to go on lock out trying to use the AC. I have removed the gas valve and burner tub to send it to someone to convert it to NG. Today we had a very warm day so I thought I would see if the AV would work. I tried to put the two wires back into the gas valve and push in the air tube which did not work. I am assuming that the air sensor is decking that the combustion chamber box is open and going into lock out. I probably will not need ac again this year I just would like to understand what is detecting that the furnace is not put together. Thanks
