Samsung AVMWH072CA0 Air Pressure Switch
The main function of an air pressure type switch is to sense if the blower is running. This pressure switch is a very critical piece of the collection of safety devices that is in place to keep you safe from any injuries. Most air pressure switches are designed with a reset that is manual instead of automatic, by which you must manually reset it before the HVAC system will continue.
Signs that the Air Pressure Switch is Already Going Bad
- Furnace can't operate at all.
- Wrong voltage range being used by the switch.
- The correct temperature is almost never attained.
