International Comfort Products NNE075F16A1 Limit Switch
The limit switch is a switch located in the furnace that makes the determination when the heated air is warmed to a point so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is because if the air never warms up the you will lose all the heat as the air flows through the ducts.
What are the clues to watch out for to know my limit switch needs replacing?
- The International Comfort Products system starts to act weird more often than not
- The HVAC system will not begin the ignition sequence or run well for any length of time
