Goodman GDS80453AN Limit Switch
The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. The limit switch contains a sensor located in the furnace that can determine when the air is warm enough for the air to begin normal home circulation.
Warnings limit switch will need replacing
- System refuses to start nor will it stay running like it is supposed to
- The HVAC system is beginning to shut down unexpectedly frequently
