LG LP090CEM Limit Switch
One big reason why limit switches are designed that way is because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts. The limit switch contains a sensor located in the furnace that can determine when the heated air is actually warm enough so that it may be pushed through the ducts and out the vents.
Some warnings limit type switch will die soon
- The heating and cooling system will not begin or will not stay running like it should
