Nordyne M1BC066 Limit Switch
A normal limit switch is a type of sensor switch in the heat exchanger that can determine when the air is warm enough that it can be circulated throughout the house. One big reason why limit switches are designed that way is because if the warmed air is too cool then you will never get hot air through the ducts.
Important clues to watch for in a bad main limit switch
- The system starts to become inconsistent from time to time
- System is unable to start or run even though the desired temperature has not been attained
