LG LMN120HE Limit Switch
A normal limit switch contains a sensor in the heating area that decides when the heated air is actually warm enough for the main blower to kick in and circulate the air. 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.
Signals of a failing main limit switch
- System will not initiate nor will it stay running as it should
- The HVAC system is starting to become inconsistent on more than one occasion
