Danby DPAC9010 Air Pressure Switch
The function of the switch is to determine whether or not the air blower is actually running. This pressure switch is part of a small, but important collection of hardware devices made to keep you from harm. Some different switches are issued with a manual reset feature, which means you have to physically reset it or the whole HVAC system will not continue operation.
