International Comfort Products PGC024K040F Limit Switch
Limit switches are crucial 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. A normal limit switch contains a sensor in the air handler that can determine if and when the air is actually warm enough for the blower to be activated.
What warnings should I watch out for to know if my limit type switch really is in need of replacing?
- The International Comfort Products system is beginning to behave differently on a regular basis
- The heating and AC system refuses to start or run for any significant length if time
