International Comfort Products NHP230AKA1 Air Pressure Switch
The reason for the existence of the switch is to sense whether the blower is actually running. Some particular air pressure switches may have a reset feature that is manual, which means it would need to be reset or the entire system will not run. This is one of many other safety creations designed to keep you from harm.
What Signs are Present when the Switch has Gone Bad
- Wrong electrical voltage being read.
- Your furnace refuses ignite.
- The expected temperature indoors seldom fully attained.
