Samsung AVMWC052CA0 Limit Switch
Limit switches are built due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch has a sensor in the heat exchanger that determines when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Key clues of an inadequate limit type switch
- System refuses to start or run for any length of time
- The whole system is starting to become unpredictable often
