International Comfort Products PGAA36C1K1 Limit Switch
A limit switch was crafted because if the air is not warm enough then you will never get hot air through the ducts. The limit switch is a switch in the heat exchanger that senses, or governs, when the heated air is actually warm enough for the air to begin normal home circulation.
Subtle cues of a poorly working limit switch
- Your International Comfort Products system is unable to start or run well longer that five minutes
- The whole system is starting to become unpredictable from time to time
