LG LS-K1830CL Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch contains a sensor in the air handler that senses, or governs, when the air is warm enough that it can be circulated throughout the house.
General indicators that your main limit switch will have to be replaced
- The system starts to run inconsistently on more than one occasion
- System refuses to kick in or will not stay running for any length of time
