International Comfort Products NDN5125BKA1 Limit Switch
Limit switches exist because if the warmed air is too cool then you will never get hot air through the ducts. The limit switch has a sensor in the air handler that senses, or governs, if and when the air is warm enough for the air to begin normal home circulation.
What happens when my limit type switch really is in need of replacing?
- The International Comfort Products system is beginning to stop suddenly time after time
- The HVAC system refuses to start or run well like it should
