Samsung AVMWC070EA0 Limit Switch
The limit switch is a switch in the air handler that determines when the heated air is warmed to a point that it can be circulated throughout the house. Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Important clues of a deteriorating limit type switch
- The heating and AC system will not begin the ignition sequence or run well longer than 10 minutes
- The Samsung system begins to become unpredictable time after time
