International Comfort Products PHAD42N1K2 Air Pressure Switch
The primary function of an air pressure type switch is to sense whether the blower is circulating the air as it should. This is one of the key aspects of the whole safety system that is intended to stop injuries or explosions. Some different switches are constructed with a manual reset, which means it will have to be manually reset before you can continue using the system.
Precursors that the Switch is Needing to be Replaced
- The expected temp is never achieved.
- The furnace or AC is unable to function properly.
- Wrong voltage running through the pressure switch.
