International Comfort Products GDL100N16A3 Limit Switch
Limit switches are built because if the warmed air is too cool then you will never get hot air through the ducts. The limit switch is a switch in the heating area that makes the determination when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Some clues main limit switch needs to be replaced
- Your International Comfort Products system refuses to start or run longer that five minutes
- The system begins to go through the startup sequence but stops quickly from time to time
