Samsung AM27B1C13 Limit Switch
A limit switch was crafted because if the air never warms up then the house will never get warm enough. The limit switch has a sensor in the heating area that makes the determination when the air is actually warm enough for the main blower to kick in and circulate the air.
Signals of a bad critical limit switch
- The heating and cooling system is unable to start or continue to run even though the desired temperature has not been attained
- The system is beginning to go through the startup sequence but stops quickly often
