Nordyne E3EX Air Pressure Switch
The function of the air pressure switch is to sense if the main blower is actually running. A lot of switches have a manual reset feature, which means it will have to be manually reset before the entire HVAC system will continue operating again. The air pressure switch is an important part of the collection of safety devices in place to keep you safe from any injuries.
