Panasonic CS-E9NKUA Limit Switch
The main reason limit switches are made is 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 makes the determination when the heated air is warm enough for the main blower to kick in and circulate the air.
Some clues of a weakening limit switch
- The heating and cooling system refuses to kick in or continue to run longer than 30 seconds
- Your system starts to act differently more often than not
