International Comfort Products T9MPD100J20C2 Limit Switch
Limit switches were created because if the warmed air is too cool then you will never get hot air through the ducts. A normal limit switch has a sensor in the heat exchanger that makes the determination if and when the air is actually warm enough that it can be circulated throughout the house.
Important clues of an unhealthy critical limit switch
- The system is beginning to become inconsistent time after time
- Your International Comfort Products system will not begin the ignition sequence or continue to run longer than 10 minutes
