International Comfort Products N9MP1125J20A1 Limit Switch
The reason limit switches exist is because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch has a sensor in the air handler that can determine when the air is warm enough to activate the main blower.
Major clues limit switch needs replacing
- The HVAC system will not start or run longer that five minutes
- The HVAC system is beginning to runs uneven time after time
