Carrier 48GS060130300 Limit Switch
A limit switch was crafted because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the heat exchanger that determines if and when the air is actually warm enough that it can be circulated throughout the house.
Simple indications of a dying limit type switch
- The system begins to act weird occasionally
- The HVAC system will not initiate nor will it stay running even though the desired temperature has not been attained
