International Comfort Products GPSM36K080F Limit Switch
A normal limit switch is a type of sensor switch in the heating area that senses, or governs, when the heated air is actually warm enough to activate the main blower. Limit switches exist because if the air is not warm enough then the house will never get warm enough.
Warnings to watch for in a failing limit type switch
- The system starts to stop suddenly often
- System will not begin or will not stay running like it should
