International Comfort Products HHP218AKA1 Air Pressure Switch
The function of the pressure switch is to determine whether the primary air circulator is doing what it is supposed to do. Some pressure switches may have a manual reset, which makes you reset it by hand or the whole HVAC system will not continue operation. This switch is just one of many devices that are created to stop injuries or explosions.
Precursors that the Air Pressure Switch has Failed
- HVAC system is unable to function properly.
- Bad electrical voltage being read from the pressure switch.
- The right temp is never achieved.
