International Comfort Products GDJ100M12A1 Limit Switch
Limit switches exist due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch contains a sensor in the heat exchanger that decides if and when the air is warm enough for the air to begin normal home circulation.
Some warnings limit type switch needs replacing ASAP
- The International Comfort Products system is starting to behave erratically on a regular basis
- The heating and AC system will not begin or continue to run for any significant length if time
