International Comfort Products H9MPV125L20A1 Limit Switch
A normal limit switch has a sensor in the air handler that senses, or governs, when the air is actually warm enough for the air to begin normal home circulation. Limit switches exist because if the air never warms up then you will never get hot air through the ducts.
