International Comfort Products H9MPD100J20C2 Limit Switch
Limit switches were created because if the air is not warm enough the you will lose all the heat as the air flows through the ducts. The limit switch is a type of sensor switch in the heat exchanger that senses, or governs, when the heated air is actually warm enough that it can be circulated throughout the house.
Key clues of a weakening limit type switch
- Your International Comfort Products system will not initiate or run longer than 10 minutes
