Nordyne E3EX Limit Switch
A normal limit switch has a sensor in the heating area that decides if and when the air is actually warm enough that it can be circulated throughout the house. This is important because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Cues of a weak main limit switch
