International Comfort Products GPSM30K080F Air Pressure Switch
The function of this type of switch is to determine whether the primary blower is on and running. Some particular air pressure switches can have a manual reset, which means you have to physically reset it or the whole HVAC system will not continue operation. This is one of many other devices that are created to keep you from harm.
How do you Know when the HVAC Air Pressure Switch has Failed
- The blower fan can not function.
- Wrong volt range running through the switch.
- The proper temperature indoors is hardly ever attained.
