Samsung ACC2400C Limit Switch
The limit switch contains a sensor in the heat exchanger that senses, or governs, when the heated air is warm enough for the air to begin normal home circulation. 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.
What are the clues to watch out for to know my critical limit switch is failing?
- System will not even start or run well longer than 30 seconds
- The HVAC system is starting to shut down unexpectedly time after time

If you decide on picking up or purchasing do your best and cross-check the correct model and also make a visual comparison so that you are positive that the correct replacement limit switch is the one being purchased. If you are not sure about the installation of the limit switch on your own then it would be in your best interest to consult a pro to do the replacement of the part.
