Samsung AVMWC032CA0 Limit Switch
A normal limit switch has a sensor in the heat exchanger that can determine if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. This is important due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
General indicators that your limit type switch will need to be replaced
- The HVAC system refuses to start or run longer that five minutes
- The Samsung system is starting to erratically from time to time
