International Comfort Products NDN5100BFA1 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that decides if and when the air is warm enough to activate the main blower. Limit switches are crucial because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
What are the clues to watch out for to know my limit type switch really is failing?
- The International Comfort Products system is starting to ramp up but then stops on more than one occasion
- System will not begin the ignition sequence or run well even though max temp has not been reached
