Samsung AVMKC035EA0 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that makes the determination when the air is warmed to a point for the main blower to kick in and circulate the air. Limit switches exist 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 signs that the limit switch most likely has a need to be replaced?
- System will not even start or run like it is supposed to
- The Samsung system is starting to initiate and then stops frequently
