Carrier 38SYG048 Limit Switch
A normal limit switch contains a sensor in the heating area that can determine if and when the air is warm enough for the main blower to kick in and circulate the air. A limit switch was crafted because if the warmed air is too cool then you will never get hot air through the ducts.
What are some indications that my critical limit switch really needs to be replaced?
- The HVAC system begins to behave differently time after time
- Your Carrier system is unable to start or continue to run longer than a minute

If you decide on picking up or ordering do your best and make sure of the correct model and also make a visual comparison in order to be sure the correct limit switch is the one being purchased. If you are unsure about the correct way of installing the new limit switch by yourself then it is probably best to contact a professional to do the work for you.
