Samsung UD18B1C2 Limit Switch
The limit switch is a type of sensor switch in the air handler that determines when the air is warmed to a point so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
Signs limit switch is in need of replacing
- System is unable to start or continue to run even though the desired temperature has not been attained
- The system is beginning to runs spotty on more than one occasion
