    Concord 80 plus gas furnace still flashing 3 flashes
    Changed out the honeywell gas valve after finding a crack in plastic housing, fired furnace back up and still getting the same 3 flashes meaning pressure switch or auxiliary limit stuck open. Looked at the schematics and followed the violet wires, removed the orange tubing, easily blew through and no water in it. Needing any and all suggestions of what to check next. All would be appreciated. Thanks
