LG A2UH243FA0 Limit Switch
The limit switch contains a sensor in the heat exchanger that decides when the heated 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 you will never get hot air through the ducts.
Indications main limit switch will eventually need to be replaced
- The heating and cooling system will not initiate or run for any length of time
- The system is beginning to go through the startup sequence but stops quickly repeatedly
