LG LS-J0910CL Limit Switch
The limit switch contains a sensor in the heat exchanger that decides when the heated air is warm enough that it can be circulated throughout the house. A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
Important signs critical limit switch has to be replaced
- The whole system is starting to runs uneven more often than not
- The HVAC system will not begin the ignition sequence or continue to run longer than a minute
