International Comfort Products NHP042GKA1 Limit Switch
The limit switch is a switch in the heating area that determines when the air is actually warm enough so that it may be pushed through the ducts and out the vents. This is important because if the air is not warm enough the you will lose all the heat as the air flows through the ducts.
Some warnings of a worsening limit type switch
- The International Comfort Products system is starting to stop suddenly often
- The heating and cooling system refuses to kick in or run well like it should
