Edgestar AP14009COM-1 Limit Switch
Limit switches exist because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. A normal limit switch has a sensor in the air handler that determines when the heated air is actually warm enough for the air to begin normal home circulation.
Key symptoms of an inadequate limit switch
- The system is starting to behave differently more often than not
- Your Edgestar system refuses to kick in or run for any length of time
