International Comfort Products N8MPN125J20B1 Limit Switch
The limit switch has a sensor located in the furnace that makes the determination if and when the air is warm enough that it can be circulated throughout the house. The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
What are some hints that my limit type switch really is not working properly?
- The HVAC system starts to act differently repeatedly
- The heating and cooling system will not even start or continue to run even though the desired temperature has not been attained
