A normal limit switch contains a sensor located in the furnace that determines if and when the air is warm enough for the air to begin normal home circulation. Limit switches are built due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.

- System refuses to kick in or run well like it should
