Delonghi PACC120 Limit Switch
The limit switch is a type of sensor switch located in the furnace that decides when the heated 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 then you will never get hot air through the ducts.
Major signs limit switch is in need of replacing
