International Comfort Products N9MP1080F16C1 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. The limit switch has a sensor located in the furnace that senses, or governs, if and when the air is warmed to a point for the air to begin normal home circulation.
Symptoms of a weak limit switch
- Your International Comfort Products system will not start or run even though the desired temperature has not been attained
- The system starts to runs spotty time after time
