Friedrich VHA24K Limit Switch
The reason limit switches exist is because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. A normal limit switch contains a sensor located in the furnace that decides when the heated air is warmed to a point to activate the main blower.
Major indications limit type switch is dead
- The HVAC system will not start or will not stay running longer that five minutes
- The whole system is beginning to runs spotty from time to time
