LG LS-K1830HL Limit Switch
A normal limit switch has a sensor in the air handler that makes the determination when the heated air is actually warm enough to activate the main blower. Limit switches were created because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Hints of a laboring limit switch
- The system begins to go through the startup sequence but stops quickly on a regular basis
- Your LG system is unable to start or run even though max temp has not been reached
