International Comfort Products NHP248GKA1 Air Pressure Switch
The reason for the existence of an air pressure type switch is to determine whether or not the blower fan is blowing air. Most air pressure switches 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 pressure switch is a very critical piece of the safety system in place to keep you safe from harm.
How to Know when the HVAC Air Pressure Switch is Starting to Go Bad
- The right indoor temperature is almost never fully attained.
- Bad voltage range running through the switch.
- The blower fan refuses to operate.
