Carrier 58MXA080F14120 Limit Switch
The limit switch is a switch in the heat exchanger that makes the determination when the heated air is warmed to a point for the air to begin normal home circulation. A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
What symptoms are present when the limit switch is dying?
- The heating and cooling system will not begin or continue to run even though max temp has not been reached
- The Carrier system starts to shut down unexpectedly more than once
