Samsung AVMBC026EA0 Limit Switch
The limit switch contains a sensor located in the furnace that decides when the heated air is actually warm enough for the main blower to kick in and circulate the air. Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
Key symptoms of a defective critical limit switch
- System will not even start nor will it stay running as it should
- The HVAC system begins to stop suddenly on more than one occasion
