LG LMU240HE Limit Switch

The reason limit switches exist is due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch contains a sensor located in the furnace that senses, or governs, when the heated air is warmed to a point so that it may be pushed through the ducts and out the vents.

What symptoms are present when the main limit switch really needs to be replaced?

The heating and AC system is unable to start or will not stay running as it should
The HVAC system is beginning to ramp up but then stops repeatedly
