International Comfort Products N9MP2080F16C2 Limit Switch
The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. A normal limit switch contains a sensor in the air handler that makes the determination when the air is warmed to a point to activate the main blower.
What to see if the main limit switch is about to stop working?
- Your International Comfort Products system will not begin or will not stay running like it should
- The HVAC system starts to erratically more than once
