International Comfort Products NNE075B12G1 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that determines when the heated air is actually warm enough to activate the main blower. This is important 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.
Main clues limit type switch should need replacing
- The HVAC system will not start or run as it should
- The International Comfort Products system starts to run erratically more than once
