Your Trane furnace has a flashing light to tell you if your unit is functioning properly or not. A steady flash is normal and means the unit is working properly. A series of flashes and pauses is a code for something wrong with your furnace. A breakdown of the flashing codes and their meanings should be located on the inner front panel of your furnace. An error code is usually a problem which requires a qualified heat tech to repair.
We get a lot of questions in the forum about furnaces that are flashing error codes -- If you'd like to have a contractor take a look at this, we can help you find one, here.
