International Comfort Products TNK100J16A1 Air Pressure Switch
The main function of the pressure switch is to see if the blower fan is doing what it is supposed to do. The vast majority of pressure switches made today may have a reset feature that is manual, from which it would have to be reset manually or the entire system will not run. This switch is just one of many devices that are created to keep you from harm.
What to Look for when the HVAC Air Pressure Switch is Starting to Go Bad
- The right temperature indoors seldom achieved.
- Furnace can't ignite.
- Wrong voltage range running through the pressure switch.
