International Comfort Products PGMD30G0908 Air Pressure Switch
The job of an air pressure type switch is to see if the air blower is actually running. Most air pressure switches are constructed with a manual reset, which makes you reset it by hand or else the system will cease to function. This switch is one of the key hardware devices made to keep you from harm.
How is it Known when the Switch is Starting to Go Bad
