International Comfort Products H8MPL125J20B1 Limit Switch
A normal limit switch has a sensor located in the furnace that decides when the heated air is warmed to a point for the blower to be activated. Limit switches are crucial due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
How can I tell if my limit switch most likely is almost dead?
- The HVAC system is unable to start or run like it is supposed to
- The HVAC system begins to stop suddenly on more than one occasion
