Samsung AVMBH052EA0 Limit Switch
A normal limit switch contains a sensor located in the furnace that can determine when the air is warm enough so that it may be pushed through the ducts and out the vents. The main reason limit switches are made is because if the warmed air is too cool then the house will never get warm enough.
Signals critical limit switch will not live much longer
- The heating and cooling system will not initiate or continue to run longer than a minute
- The Samsung system starts to act weird from time to time
