Friedrich MW30C3G Limit Switch
The limit switch is a type of sensor switch in the air handler that senses, or governs, when the air is warmed to a point for the main blower to kick in and circulate the air. Limit switches exist due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
Cues of a declining limit type switch
