International Comfort Products PGS Air Pressure Switch
The main job of this type of switch is to determine whether the blower fan is doing what it is supposed to do. This is one of the critical aspects of the whole safety system that is intended to stop injuries or explosions. Some different switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running.
Symptoms that your Pressure Switch is Needing to be Replaced
- The blower is unable to operate properly.
- The right temp is hardly ever fully attained.
- Wrong volt reading from the switch.
