International Comfort Products GDL075N12A1 Limit Switch
The limit switch is a type of sensor switch located in the furnace that decides if and when the air is warmed to a point to activate the main blower. The main reason limit switches are made is because if the air is not warm enough then you will never get hot air through the ducts.
What are the signs that the chief limit switch really needs to be replaced?
- The whole system is starting to erratically more than once
- System will not even start or will not stay running like it ought to
