Sanyo XS1271 Limit Switch
A normal limit switch has a sensor located in the furnace that decides when the 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 inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
What signals that my chief limit switch has a need to be replaced?
- The system is starting to shut down unexpectedly repeatedly
- The heating and AC system will not initiate or will not stay running for any significant length if time
