    Where is the furnace located? something has happened to cause the furnace to not get enough air

    It won`t hurt to leave the door off,as long as there nothing close by that is flameable, JUST until you can get more info as how to fix, I`ve seen people run them for years with no door, as long as the door that covers the blower compartment is closed

    Can you post some pics of your furnace and furnace vent, along with the top furnace cover (which you have removed)?
