|Coleman 4030 furnace problem||Arthur Allison||12-30-13|
|Furnace works fine but gets really hot and trips limit switch. Do I have an exhaust blockage?|

|More likely that you have an air flow problem due to blocked duct, slow running fan motor, and so on.|
Check to make sure all dampers are open and no rugs or carpets over them.
Change the limit switch as they do go bad on ocaision, it is a common failure.
