Samsung UQB12JJWC Limit Switch
The limit switch is a type of sensor switch in the air handler that makes the determination when the air is warmed to a point for the main blower to kick in and circulate the air. The main reason limit switches are made is because if the warmed air is too cool then you will never get hot air through the ducts.
