Carrier 50JX048300 Limit Switch
The reason limit switches exist is because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. The limit switch is a switch in the heating area that decides if and when the air is warmed to a point for the blower to be activated.
What signals that my limit type switch really is almost dead?
- The heating and AC system is unable to start or run for any length of time
- The whole system begins to become unpredictable repeatedly
