International Comfort Products N9MPD040F08A2 Limit Switch
Limit switches are built because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch contains a sensor in the air handler that decides when the air is warmed to a point for the air to begin normal home circulation.
What are the signs that the critical limit switch is about to go out?
- The HVAC system starts to act weird often
- Your International Comfort Products system will not initiate or run longer than 30 seconds
