Frigidaire FRS123LC1 Limit Switch
Limit switches exist due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. A normal limit switch is a switch in the heating area that determines if and when the air is actually warm enough to activate the main blower.
What are the clues to watch out for to know my limit type switch really needs to be replaced?
- The HVAC system refuses to start or will not stay running like it is supposed to
- Your system begins to shut down unexpectedly often
