LG LS-K2430CL Limit Switch
Limit switches are built due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. A normal limit switch contains a sensor in the air handler that senses, or governs, when the heated air is actually warm enough to activate the main blower.
Elements of a weakening limit type switch
- The whole system is beginning to act weird frequently
- The heating and cooling system refuses to kick in or continue to run longer that five minutes
