International Comfort Products HHP018GKA1 Air Pressure Switch
The reason for the existence of an air pressure type switch is to determine whether the blower fan is running. This pressure switch is one of the key hardware devices made to stop injuries or explosions. Various air pressure switches can have 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.
Signs that the System Pressure Switch is Going Bad
- The expected temp is rarely fully achieved.
- The blower can not operate.
- Inaccurate volt reading from the switch.
