International Comfort Products GNL125N20C1 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that can determine when the heated air is warmed to a point for the blower to be activated. Limit switches were created because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Main clues critical limit switch will have to be replaced
- The heating and cooling system will not initiate or continue to run longer than 30 seconds
