Samsung AVMBC020EA0 Limit Switch
Limit switches are crucial because if the air is not warm enough then you will never get hot air through the ducts. The limit switch is a switch in the heat exchanger that senses, or governs, when the air is actually warm enough for the air to begin normal home circulation.

- The system is starting to runs uneven on more than one occasion
