International Comfort Products PGF048K120F Air Pressure Switch
The reason for the existence of the pressure switch is to sense if the main blower is on and running. An air pressure switch is one of many other safety creations designed to keep everyone in the house safe. A good number of pressure switches today are issued with a manual reset feature, by which you must manually reset it before the HVAC system will continue.
Signs to Look for when your Pressure Switch is Needing to be Replaced
- The blower can not function properly.
- Wrong electrical voltage running through the switch.
- The right temperature indoors is hardly ever attained.
