Samsung AM27B1C07 Limit Switch
A limit switch was crafted because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. The limit switch has a sensor in the heat exchanger that decides when the air is warmed to a point for the air to begin normal home circulation.
How do you know if your limit switch most likely is not working properly?
- System will not begin the ignition sequence or run as it should
- The whole system starts to go through the startup sequence but stops quickly repeatedly
