Samsung MH080FXCA4A Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that can determine when the air is warm enough for the air to begin normal home circulation. Limit switches are crucial because if the air is not warm enough the you will lose all the heat as the air flows through the ducts.
What signals that my main limit switch is about to stop working?
- The heating and cooling system refuses to start or run longer that five minutes
- The whole system starts to stop suddenly more than once
