Carrier 38YSA024 Limit Switch
A normal limit switch is a type of sensor switch in the heating area that determines if and when the air is warm enough for the blower to be activated. The reason limit switches exist is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
What are the clues to watch out for to know my limit type switch really is about to stop working?
- Your Carrier system will not start or run well longer that five minutes
- The system is beginning to become unpredictable repeatedly
