International Comfort Products NBF100F20A1 Limit Switch
Limit switches are crucial because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. A normal limit switch is a type of sensor switch in the air handler that determines when the heated air is warmed to a point for the blower to be activated.
How do you know if your main limit switch really needs to be replaced?
- The system starts to act weird occasionally
- The HVAC system refuses to kick in or run even though the desired temperature has not been attained
