International Comfort Products NTN3125KJA1 Air Pressure Switch
The function of the pressure switch is to see if the primary air circulator is circulating the air as it should. This is just one of many devices that are created to keep you safe. Some different switches are equipped with a manual reset feature, from which it would have to be reset manually or the entire system will not run.
What to Look Out for when the System Pressure Switch has Gone Bad
- The furnace can not operate at all.
- Wrong voltage range running through the pressure switch.
- The right temp seldom fully achieved.
